JEE Advanced 2026 Chemistry question

The correct order of ONO bond angle in the given species is

(A)NO < NO < NO < NO
(B)NO < NO < NO < NOCorrect
(C)NO < NO < NO < NO
(D)NO < NO < NO < NO

Answer: (B)

Solution

Count the non-bonding electrons on the central nitrogen; the greater the repulsion they exert, the more the bond angle is squeezed. * **NO** (nitronium): hybridised, **no** lone pair or odd electron on N **linear, **. * **NO** (nitrogen dioxide): one **odd (single) electron**
