JEE Main Chemistry question

The molecule having the smallest bond angle is:

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

Answer: (B)

Solution

For pyramidal molecules with one lone pair, the bond angle decreases down a group as the central atom's electronegativity decreases (by Bent's rule, the lone pair draws more -character as electronegativity falls, pushing the bonding pairs into more -character
