Symmetry point group

[@doctorcomrade2194]

Thanks so much, this is how point groups should be taught!

Thanks for the complements!

This topic was teaching in my college bt I didn't understand but now is very clear to me

[@sarveswaran2009]

Wow, born teacher. Excellent explanations. Thank you Sir.

[@shabirhussain176]

What a superb video... All concepts in just one video... Watching this video is an upper hand than watching all other videos of this topic on KZbin.... You are great sir... God bless you.. Thank you so much❤❤❤.

[@ChemWis]

Thanks for watching this video! there are many more interesting videos on different topics, you can find them by going through my playlist. Keep watching!

[@123xjd3n]

Very helpful, I thought I understood the concepts until I did the examples. The examples help a lot, I found a pattern now

[@ChemWis]

Glad it helped!

[@shaniaakhternoor1813]

You are really a teacher, if i got a change i must salute you

[@Thekemparmar]

It can very very helpful, Thank you sir☺😊☺😇

Excellent teacher! This helps so much! Thank you!

Best way of explaination 🔥🤗🤗

[@ChemWis]

Glad you think so!

[@mimiait]

Thank you for your explanation. I have a question related to the example in the minute: 14:34. On the previous video (right before this one) you have stated that the same molecule has a C6 and a sigma h symmetry, while on this one it is said that it has a C3 and no sigma h symmetry. Which is a bit confusing ! I'll be very grateful if you can explain it. Thank you in advance.

Dude thank you so much everything clear now

[@ananthivivegam3367]

Awesome sir

[@chetnapathadiya2519]

Can u plz help with what will be the point group of only Dibenzene Which means 2 benzenes rings are connected with only 1 bond?

[@thorneeva5321]

something is wrong: at 6:20 you say NO2 belongs to "c infini v" but it s C2v because it is non linear

[@ChemWis]

Dear Eva, I have talked about N2O and not about NO2. Please revisit my lecture to clear your confusion

[@thorneeva5321]

@@ChemWis indeed you re right sorry

[@PritomAhad]

Sigma h means improper axis of rotation horizontal?

[@chempaklel6704]

Yes

[@Professional_chemist]

Thank you so much sir.

[@DragonWarrior1524]

Im kind of confused on where the sigma plane was at 1:31

[@DragonWarrior1524]

lol nvm found a source and i guess the plane bisect the Cl and Br atoms

[@selvimurugesan9513]

Sir make, more videos in group theory

Hi ! We dont have a sigma in CH2ClBr ..the réflexion of Cl must be Cl and not Br Thnx for explaining this it was so.good ❤

Thanks for your complements!

Plane will pass through C ,Cl and Br and reflect both hydrogen

[@pujakumarisingh3136]

Sir dnh ka matlab

[@akansha123.4]

More than one axis of rotation and horizontal plane perpendicular to principal axis

[@zeeshanmanzoor4717]

Water has Sigma horizontal

[@ChemWis]

σh means a plane perpendicular to the principal axis. In water the principal axis is C2 and there is no plane perpendicular to that axis. So, water does not have σh

[@Maryam_Khalid_g6i]

You reply to only those who appreciates you😂😂😂 If someone ask a question, you simply ignore You failed as a teacher 😢

[@ChemWis]

Thank you for the comments. I will try to become a good teacher.

[@samar_moh08]

Hi... Thanks for your video❤️ but the last example your answer was D3d! It should be D3h becouse we have Sigma d

[@ChemWis]

Thank for your comments. As I remember, the last example is related to the point group of allene. It has D2d point group due to the presence of Sigma d. For Dnh point group the molecule must have Sigma h. Please revisit this video for more clarifications.

[@shamuelaandriani3429]

Wrong! there is no sigma h so why would you group it as D3h? D3d is correct

[@BewithUs-hd2ni]

No one explain that how c2 is perpendicular to principle axis howwwww everyone just say it no one explain it i dont get the answer yet how do we know that c2 is perpendicular to principles axis 😢😢😢😢😢😢😢😢😢😢😢😢
