This is the best view to make the students understand. Thank you

[@noorshidamohdali]

Thank you

[@Abdulhalim-mg6wz]

I would like to say that you have done a great job and made it understandable. Thank you.

[@noorshidamohdali]

Thank you so much. Hope it helps you

I suggest those who found it helpful to share these videos with your friends. I don't know the Miss but her job is brilliant. I think it is a good way to appreciate her job and efforts for students. Thank you

[@noorshidamohdali]

Thank you so much coz you appreciate to what I did. Hope it helps the others too

[@ChemistryMajor]

Best explanation 🎉

[@noorshidamohdali]

You're welcome. Hope it helps you

[@shanianu4139]

Thank u so much❤️ none of the videos I watched was clear as yours..this is great. I was struggling so much with symmetry

[@noorshidamohdali]

Thank you. Hope it helps you

[@anaclararibeirodesouza1916]

best video of symmetry in the entire internet!! THANK YOU

[@noorshidamohdali]

Thanks ana. Hope it helps you

[@chichiria_cindysunflowers3723]

You teach better than my teacher. Thanks a lot

[@noorshidamohdali]

Thank you. Hope it helps you

nice way to explain symmetric compounds. ...great job❤

[@noorshidamohdali]

Thank you! 🙂

[@SoberekonEmmanuel-nc8vh]

Nice one! Pls can you make other videos of more difficult complexes. Tnks

[@noorshidamohdali]

Thanks. Hopefully I plan for next videos.

[@AbyPaulBenny-fr1xv]

the difference between a symmetry element and operation is not specified. At the end you said there are symmetry element operations for this BF3 molecule. are both elements and operations same?

[@mishras8360]

So well explained so many confusions I had before watch your vdo

[@noorshidamohdali]

Thank you. Hope it helps you

[@Naveenbabuborugadda]

Thank you sis for best explanation.

Appreciate your work.

[@noorshidamohdali]

Thank you so much

[@azsk4974]

Informative video. But in the video of Ammonia you did not mention about C2 axis while there is 3c2 like this one. I hope you will review that and correct . Thank you.

[@noorshidamohdali]

Thanks for the comment. Yes in my ammonia video I didn't mention 3C2 because ammonia is trigonal pyramidal shape. It's not planar so impossible to rotate 180 degree at N-H bond. So no 3C2 symmetry elements for ammonia. Thank you

[@azsk4974]

@@noorshidamohdali thank you ma'am for clearing the confusion. if you could do something of PtCl4(symmetry) that would be great.

[@aasifsvlog373]

Great way of teaching

[@noorshidamohdali]

Thank you. Hope it can help

[@SaqibUrRehman-o5i]

Is BF3 and AlCl3 have the same symmetry and symmetrical operation

[@noorshidamohdali]

Yes

[@biswajitdutta5917]

What about S3^2? Or C3^2

[@fayanjuomobobola]

Great explanation!🙌

[@noorshidamohdali]

Thanks. Hope it helps

[@fayanjuomobobola]

@noorshidamohdali Yes. Very helpful.

[@Olga-gs5lc]

You have a lovely voice

[@ankitachakraborty1239]

From where did you buy the equipments to make this model please tell me please please

[@noorshidamohdali]

I bought from online shopping. chemistry molecular model

[@NeoUno866]

They’re called molymods I believe

[@goodvibes66880]

Nice

Does BF3 not have sigma D?

[@zainalabideenmohamed5964]

Yes, It does

[@miniaturerealcooking9103]

Mam Bcl3 mein bi kia yahi symmetry elements hon gy???

[@noorshidamohdali]

can you please ask in English? Thank you

[@miniaturerealcooking9103]

Are Bcl3 has same symmetry elements as in Bf3???

[@noorshidamohdali]

@@miniaturerealcooking9103 yes same coz it has same geometry shape trigonal, planar with same terminal atoms

[@sajju084]

How come C1?

[@noorshidamohdali]

C1 can be at central atom or passing through the B-F bond. Infact C1= E =C3 +3 (rotate clockwise 3x120 degree) = C3-3(rotate anticlockwise 3x120 degree)

[@apcreation5626]

Tbq

[@nethranraj2991]

why no C2 axis in NH3

[@noorshidamohdali]

NH3 is not planar molecule. So we cannot rotate 180 degree through the N-H bond

[@sindhucrsindhucr9881]

Mam can you say improper axis of rotation please mam

[@noorshidamohdali]

Hi..... As I stated in minute 5:40, this molecule contains S3. Is this an answer to your question?

[@rojaroja9921]

Thank you teacher garu

[@noorshidamohdali]

you're welcome

[@eiiii0]

Does BF3 not have sigma D?

[@noorshidamohdali]

BF3 doesn't have sigma d. There are 3 sigma v because the planes parallel to main axis C3 and also the planes do not bisect the angle between between two C2 axes
