Incorrect order about bond angle is :
Text Solution
Verified by ExpertsThe correct answer is:
C
According to VSEPR theory as electronegativity of central atom decreases, bond angle decreases. So bond angle of H 2 O > H 2 S > H 2 Se > H 2 Te
C 2 H 2 > C 2 H 4 > CH 4 > NH 3 . In NH 3 there is bp-lp repulsion so bond angle decreases to 107º from 109.5º.
sp sp 2 sp 3 sp 3
180º 120º 109.5º 107º
SF 6 < NH 3 < H 2 O < OF 2 in this case bond angle of NH 3 is highest because lp - lp repulsion is absent in. it.
BF 3 > H 2 O > H 2 S > SF 6
> 
> 
sp 2 sp 3 sp 3 sp 3 d 2
(104.5º) (92º) (90º)
