The decreasing order of bond angle in the following molecules is

(A) > >
(B) > >
(C) > >
(D) > > Correct

Answer: (D)

Solution

All three central atoms are hybridised, so the ideal angle is , but lone pairs repel more strongly than bond pairs (lp-lp > lp-bp > bp-bp) and squeeze the bond angle. has 4 bond pairs and no lone pair: . has 1 lone
