polarity – without using electronegativity, which one of – Therefore, it is non-polar. $\ce{XeF2}$ This one is linear – no net dipole moment, so it is non-polar. $\ce{XeF4}$ I could only find the ball-and-stick model for this one. It is square planar – there is a lone pair of electrons (not shown) on each "face" of the square on Xe. There is no net dipole moment, so it is also non-polar.Labels: how to determine if a molecule is polar or nonpolar, how to determine if a molecule is polar or nonpolar from lewis structure, how to determine if a molecule is polar or nonpolar given its structure, how to determine if a molecule is polar or nonpolar khan academy, how to determine if a molecule is polar or nonpolar usingHow to analyze the geometry of a molecule to decide whether a molecule that contains polar covalent bonds is polar or non-polar overall.

Predicting bond type (metals vs. nonmetals) | AP Chemistry | Khan Academy – Ötən videomuzda Biz atomlar arasındakı əlaqələr mövzusuna giriş etdik Və bu əlaqələrin tiplərindən danışdıq: İon, Kovalent və Metal Bu videomuzda biz müxtəlif atomlar arasında yarana biləcək rabitə tipləri haqqında biraz daha ərtaflı danışacayıq.
Bunu aydın başa düşmək üçün, mən elementlərin geniş təsnifatından istifadə edəcəm. Ümumi olaraq, biz maddələri metallar və və qeyri-metallara bölündüyünü fərz edəcəyik. Dövri cədvələ müraciət etməzdən əvvəl bu sualları cavablandıraq Metallar və qeyri-metallar nədir? və onların arasındaki olanlar metalların xassələri nələrdir? Ümumiyyətlə, mettallar elektrik keçirir. Elektrik Keçirirlər. Onlar elastikdir, başqa sözlə desək mettaları qırmadan əyə bilərik. Və ümumi desək, ( istisnaları da var) onlar otaq temperaturunda bərkdirlər. Beləliklə, mən onların otaq temperaturunda bərk halda olduğunu deyirəm İndi isə, qeyri-metalların xassələri haqda nə düşünürsüz ? Ümumi olaraq desək, onlar mettalların tam əksi olacaq Qeyri metallar, bir çox halda otaq temperaturunda bərk halda deyil, bir çox halda qazdır. Elektrik keçirmirlər. İndi isə dövri cədvələ nəzər yetirək, Metal və qeyri-metalları necə ayırırıq ? Bunu ayırd etmək üçün cızıqlı sarı xətdən istifadə etmişəm. Beləliklə, sarı xəttin üstündə və sağında olan elementlər qeyri metallardır və dövri cədvəli dolduran elementlərin rənglərinə diqqət etsək, sarı rəngdə olan bütün elementlər; Hidrogen, Karbon, Azot, Oksigen, Flüor, belə davam edir bunlar hamısı qeyri metallardır Və ümumi olaraq desək. otaq temperaturunda onlar qaz halında olacaq və elektrik keçirməyəcəklər Mavi rəngdə olan elementlər nəcib qazlar adlandırırıq və onlardan başqa videomuzda danışmışıq. Beləliklə bunlar qeyri-metallardır. Dövri cədvəli quran inslanlar, hər bir elementi (nəcib qaz) öz rənginə uyğun qeydə alıblar çünki onlar qeyri metalların bir alt sinfi kimi baxa bilərik və onlar inertdir, başqa sözlə desək başqa elementlərlə əlaqə qurmurlar. Və onlar heç bir rabitə yaratmırlar Beləliklə, yerdə qalan elementləri metal olaraq qəbul edə bilərik və rənglərin müxtəlifliy metalların alt qruplarının olmasından qaynaqlanır ama ümumi olaraq desək, cızıqlı sarı xəttin altındakı bütün bu gördünüyünüz elementlər ümumi olaraq desək, elektrik keçirir,elastikdirlər və otaq temperaturunda bərkdirlər. Cızıqlı sarı xəttin tam üzərində yerləşən və rəngləri mavimsi-yaşıl rəngdə olan elementlər metalloidlər kimi bilinir Çünki onlar həm metal, həm də qeyri metal xassələrinə malikdir. Ümumi desək, əgər biz reaksiya girən elementin metal və qeyri-metal olduğunu bilsək hansı tip əlaqə növünün yarandığını bir çox hallarda praqnozlaşdıra bilirik. Misal olaraq, əgər metal, metal və qeyri-metal, və metal arasında əlaqə varsa hansı əlaqə tipinin yarandığınl düşünürsüz ? Əgər metal və qeyri-metalı bir araya gətiririksə biz bu misalı birinci videomuzda görmüşdük Natrium metalınl və Xlor qeyri-metalını, biz görürük ki,xlor elektronu özünə çəkir, və Sodium, 1ni itirir. Daha sonra Xlor atomu Xlor anionuna çevrilir və Natrium atomu Natrium kationuna çevrilir, ,onlar bunlar bir birini cəzb edir və ion rabitəsi yaradırlar. Bu rabitə növləri ion rabitələri yaradır İndi isə qeyri-metallar arasındaki əlaqəyə diqqət etsək nə görərik? İki qeyri metal birləşir bu sözü deməkdə çətinlik çəkirəm iki qeyri metal birləşir Nə baş verəcəyini düşünürsüz ? Ilk videomuzda gördük ki, Oksigenləri birləşdirdikə nə baş verdiyinə diqqət etdik Biz gördük ki kovalent rabitə yaranır və ümumi olaraq desək qeyri metalları əlaqə qurduğu zaman kovalent rabitə yaranır. Və son olaraq, bu ən aydınıdır iki metaldan hansı rabitə tipinin yarandığını düşünürsünüz ? Təsəvvür edə bilərikki bu metal rabitəsi olacaq hansı ki bu halda elektronlarını paylaşır və buna görə elektrik keçirirlər və plastikdirlər. Burda sonlandıraq Bugün danışdığım hər bir şeyin istisnası var ama ümumi olaraq desək, bunlar sizə başlangıc olaraq kömək edəcək. .

Identifying Intermolecular Forces 1 – This is a short tutorial on how to identify the intermolecular force the predominant intermolecular Force in a molecule so just as a refresher there are three types of intermolecular forces if The Molecule overall is Nonpolar.
Then it's only intermolecular Force is the London dispersion Force which as you will remember is the weakest intermolecular force if The molecule overall is polar and has no possibility of Hydrogen bonding in other words it does not contain a Hydrogen bonded directly to either a fluorine oxygen or nitrogen Then it has its predominant intermolecular Force is the dipole-dipole Attraction if the molecule is polar and it Can hydrogen bond that is it contains hydrogen's directly bonded to either fluorine oxygen or nitrogen? then its predominant intermolecular Force is hydrogen bonding, so [let's] look at some examples that are going to help you There is one worksheet with answer t posted already on identifying in a molecular course that's kind of basic, and I'm going to post The ones I'm going to be working examples from right now. Just for a little bit more depth Alright, so how do we go about identifying the type of intermolecular force the first thing you want to do always is draw the Lewis Structure don't try to try to get out of doing that or you will make mistakes why do we do that you need to draw the Lewis structure in order to determine the shape of the molecule [and] it is the Three-dimensional shape of the Molecule that Determines whether it's symmetric or not? Once you've drawn the shape and determine the symmetry you will be able to know if it's a polar or nonpolar Molecule let's do a couple of examples if you watched my other short little video and Drawing molecular shapes and Lewis structures the example one of the examples. I did there was sulphur dioxide and the Lewis structure of sulfur dioxide looks like this and Once we have that drawn You can see that it is not a symmetric shape [if] you look on your molecular shape chart in your textbook [in] This molecule sulfur has three electron domains which gives it a trigonal planar Electron domain shape and just looking at the atoms without paying attention to the nonbonding pairs That molecular shape is bent, [so] it is not a symmetrical molecule therefore it is polar and Since it's polar with no possibility of Hydrogen bonding its main intermolecular Forces dipole-dipole Water which should be easy for all of you now has the Lewis structure That looks like this [its] molecular. Shape is also bent Anytime you have a bent structure It is not symmetrical even though it looks the same if you were to draw a plane up and down if you drew a plane across the middle It doesn't look the [same] top and bottom so it has to be symmetric from all angles and planes in order to be considered totally symmetric, so anyway water is not symmetric and So it's polar And it also contains the possibility for hydrogen bonding in other words It has an oxygen directly bonded to a hydrogen So the main intermolecular force for water is hydrogen bonding the next one a molecule, or the formula is Ch2Cl2 it's kind of like it's similar to Methane Ch4 Now Methane would be nonpolar It's all carbon Hydrogen but it's also methane would also be symmetric if we draw out the tetrahedral shape of Ch2Cl2 it's actually not symmetric, so You could draw Dipoles and when you draw a dipole they all the arrow always points to the more electronegative atom You can see the dipoles you have four highly electronegative chlorine that this overall molecule And [that] in there are my dogs has a net polarity or dipole in one particular direction. So it is [a] polar molecule it Cannot hydrogen bond because although it does have hydrogen atoms They are not directly bonded to either fluorine oxygen or nitrogen So the main intermolecular force in this molecule is Dipole dipole The next one is very interesting [you] should be able to draw the Lewis structure and the shape for this the formula Given is just s co s [co] and Kind of looks like Carbon dioxide which we'll talk about in a minute, but the shape of this is linear now linear if The outside atoms are identical would be Symmetric, but in this case you have two different atoms on the ends and oxygen and a sulphur, so it is not symmetric Therefore it is polar there are no, hydrogen's, [so] the Main Intermolecular Forces Dipole-Dipole I Drew Carbon dioxide down at the bottom because it's such similar structure to the Sco [in] this case though because you have oxygens on both Ends, the structure is symmetric and therefore carbon dioxide is nonpolar so carbon dioxide Even though it has as polar bonds both of these carbon Oxygen bonds are polar They oppose each other they cancel out So there is no net polarity to carbon dioxide and it only has london dispersion forces All right couple more Phosphorus Trichloride [if] you draw the [Lewis] structure you discover there is a nonbonding pair of electrons on the phosphorus and Let's see the electron domain. Shape would be tetrahedral, but the molecular [shape] that's when you ignore the nonbonding pair and would have a Trigonal pyramidal shape it is not symmetric, okay? Mainly if you think about putting a mirror here the top and bottom are not identical it's not symmetric therefore is polar and Dipole-Dipole are the main intermolecular force the last one I wanted to do Is Sulfur trioxide? Sulfur is one of the elements [that] very Regularly expands its octet to hold more than eight valence electrons. You can see in this structure [two] four six eight ten twelve Valence electrons around the Sulfur which is fine [and] So the shape of this is trigonal planar Okay, that means all of these bonds are in the same plane, and so although you have three polar bonds They all cancel out and so there's no net [Dipole]. No net Polarity and sulfur trioxide [it] is symmetric It's nonpolar and therefore the only intermolecular Force that can have is London dispersion That is it for identifying intermolecular forces .
