Dear students, this question is based on the diagram given here.
00:04
So the first question is, label all missing lone pairs.
00:10
Here all missing lone pairs you have to label.
00:12
So oxygen has two lone pairs.
00:16
Each oxygen has two lone pairs.
00:21
Nitrogen is having a single lone pair.
00:25
This is also because it is having five electrons.
00:30
All other carbon and hydrogen, they don't have any lone pair.
00:34
Next is, state the hybridization and molecular geometry of the atoms indicated with a and b.
00:40
A, this is a, this nitrogen, here all single bonds, therefore a is sp3.
00:48
Hybridization is sp3.
00:51
And molecular geometry? molecular geometry is tetrahedral.
01:00
Because here one lone pair is there, so it is b pyramidal.
01:04
It is electronic geometry is tetrahedral and molecular geometry is pyramidal.
01:10
Then coming to b, b is this carbon.
01:15
This carbon is also sp3.
01:17
It is trigonal...
