Bieng honest mam, I understood 95 % + concepts because of ur teaching. I haven't completely read the chapter. Thank u so much mam 👍. If I would hv been ur student in 11 & 12th, I may have topped in my school. Thank you for free Education, because many of them can't even afford it. . . . . & I m 1 of them.

I like ur way of teaching...😊

[@Khushi-fe7jc]

thank you so much ma'am for your explanation ,but ma'am i've doubt about hydrogen peroxide molecule "it doesn't have horizontal plane of symmetry"

[@saswatkumarpati6109]

Mam, H2O2 will has open book structure with dihedral angle of around 110 degrees. So all 4 atoms do not lie in the same plane, thus there is no horizontal POS. So, it is C2 and not C2h. Please rectify me if I’m wrong. This tutorial series has been very helpful. Thank You.

ma'am while explaining NH3 point group, you have drawn the cartesian system incorrect( x,y,z axis). x,y,z axis should be such that cross product of x,y should give z , cross product of y,z should give x and cross product of z,x should give y.......btw your lecture videos help a lot

Madam,h202 is skew structure molecule with dihedral angle 111.5* so how can it be planar and contain sigma h???🤔

Mam 13:18 sec pe jo example dicuss ker rhe ho usme c4 kese hoga compound organic h to planer nhi hoga na

[@shardashirke5005]

Ma'am H2O2 ke eg mein Axis C2 hoga yeh 180 degree rotation ke wajah se voh toh samjh gaya but ma'am aap ke trick ke according toh 2 o and 2 h atoms ke position change horahi h then uske hisab se C4 hona chahiye na?

[@dr.suboothairatdr.mehvashz1317]

C4 nhi hoga, because agar 90 degree rotate karenge toh sab atoms ki position change ho jaegi.

Im having the same doubt

[@nabeehafatima9607]

@@dr.suboothairatdr.mehvashz1317 but according to her trick she said we can consider the atoms moving and that will be the value of n. So it is contradicting her first trick. But as u said C4 is not possible that i understood. Maybe her tricks aren't to be applied everywhere

mam one correction , h2o2 ka point group C2 hai ............ it can't be Cnh, because it is a non planner structure it should not contain any plane.

[@shubhamgodiyal4706]

Ma'am H2O2 is not a planar molecule so it does not contain sigma'h' plane of symmetry hence it belongs to C2 point group and H3BO3 is planar and so it does have sigma'h' hence it belongs to C3h point group
