great job Noorshida Maam
thanks. hope it helps you
I am having a hard time understanding why it doesn't have a center of inversion. Specifically, why isn't the half-way of the bond connecting the two oxygen atoms a center of inversion?
i dont understand the difference between sigma h and sigma v when you put them below the molecules could you explain that more ?
this video is a blessing thanks you
Thank you. Hope it helps you
You teach better than my teacher. Thanks a lot
Thank you. Hope it helps you
Very good video. may i know where to buy the kit?
Actually the 3D model available at shoppe / lazada. But here I did modification to include the axis
Tqvm
Thank you so much
You're welcome. Hope it helps you
MAM have you whats app or gmail account plzz mam i want ask something
Thank you sooo much ❤❤❤❤ I understood it finally😊
Thanks. Hope it helps you
What about S3^2? Or C3^2
C1 MEANS E. SO C1 DOESNT HAVE ANY REQUIREMENT
yes correct equivalent. thank you. so you can write either C1 or E. Here I just point out that at C2 axis also we can rotate 360 degree for C1
Thank you ma'am
my professor should learn from you ):
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
There is nothing like S1,S1 is actually a sigma plane, also S2= inversion,,yes there are S3 and S6, but no S1 or S2 (they dont exist)
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
