Hope it helps you😀

Mam if a compound contains pos then why it is called optically inactive??
SQUARE PYRAMIDAL POINT GOURP IS ????
❤❤ Thank you
You're welcome. Hope it helps you
Best explanation 🎉
You're welcome. Hope it helps you
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?
Thank you 🤍
Thank you so much, very helpful!!! ❤
Please upload more thank you so much🎉
Thanks. I'll do
I love your voice! Easy to follow you.
Thank you. Hope it helps
Thank you sis for best explanation.
You're welcome. Hope it helps you
Is BF3 and AlCl3 have the same symmetry and symmetrical operation
Yes
Thanks for the video
You're welcome. Hope it helps you
Does BF3 not have sigma D?
Yes, It does
Does BF3 not have sigma D?
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
Thanks for your kind explanation. I have two question, 1. In this case, sigma h / i / S2 these three operations are same. Despite these facts, should we say all of them for its symmetry operations? 2. It seems like infinite sigma v planes bisect infinte C2 axes. So, wouldn't it be correct to write them as sigma d planes?
Q1: i = S2 but sigma h is another symmetry element operation Q2: No because if sigma d, the plane should bisect the angle between two C2 axes. This molecule has infinite C2 instead of 2
Thank you so much 😊
you're welcome. Hope it helps
Mam can u tell in bh3
Nyc ❤
great explanation. however the last 3 min isn't working for me
I'm really sorry. It should be a technical problem. I'll try to fix it. Thank you
TQ Dr shida Masa sy bljr inorganic chemistry dulu dgn cik shida sudahnye sy nak paham X nampak. Bila ad video so visualise chemistry baru jelas
Susah kan tcer Hani. Sbb 3D tidak semua orang boleh nampak dengan mudah. Imaginasi perlu tinggi. Sy selalu fikir macam mana nak bantu pelajar. It takes time.
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
Thank you so much coz you appreciate to what I did. Hope it helps the others too
Appreciate your work.
Thank you so much
Good explanation. Your videos are really helpful for me. Thanks a lot❤
Thanks. Hope it helps you
I am impressed ❤
Thanks. Hope it helps you
thank you for this video. you're a nice teacher.
You're welcome. Hope it helps you
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.
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
@@noorshidamohdali thank you ma'am for clearing the confusion. if you could do something of PtCl4(symmetry) that would be great.
why does C3 work when the double bond is no longer in the same place. Is it because of resonance?
Yes correct
They haven't taught me about diagonal plane and S1 , S2 , S3 sort of things those were new
Nice explanation
Thanks. Hope it helps you
Nice one! Pls can you make other videos of more difficult complexes. Tnks
Thanks. Hopefully I plan for next videos.
Great explanation!🙌
Thanks. Hope it helps
@noorshidamohdali Yes. Very helpful.
thanku mam
You're welcome. Hope it helps
Wow dr ..clearly can understand..thank you so much dr...and i am one of your previous UPSI Student as well
Thank you misha 😊. Perhaps will see you some other day. Hope this helps you
@@noorshidamohdali 😁sure dr..take care
thank you so much!!
best explainer
Thank you. Hope it helps you
could you explain why the planes are sigma d but not sigma v? your videos really help me a lot, thank you so much.
Sigma d because that planes bisect the angles between two C2 axes
C2 is along z axis or y axis
if we look the molecule from the side view, C2 axis is along z axis
Thanku you ma'am ❤✌
You're welcome. Hope it helps you
best video of symmetry in the entire internet!! THANK YOU
Thanks ana. Hope it helps you
very nice thanks a lot noorshida mam
Thanks. Hope it helps you
Mam don't stop uploading video please please please please because it was very helpful
Thanks Rithika. Hope it helps you
your voice ❤
nice way to explain symmetric compounds. ...great job❤
Thank you! 🙂
How come C1?
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)
Great way of teaching
Thank you. Hope it can help
Mashallah 💖
Thank u so much❤️ none of the videos I watched was clear as yours..this is great. I was struggling so much with symmetry
Thank you. Hope it helps you
Love u 😍💕💕💯
