Question

The ONO angle is maximum in

(a) NO₃^-

(b) NO₂^-

(c) NO₂

(d) NO₂⁺

Answer 1

Correct option  (d) NO₂⁺

Explanation:

The actual geometry of the NO₃^- ion is trigonal planar with bond angle of 120° Hybridisation is sp².

NO₂^- :Ideal geometry is trigonal planar, sp² hybridisation with bond angle of 116°.

NO₂ :ldeal geometry is trigonal planar sp² hybridisation with bond angle of 134°.

NO₂⁺ : Ideal geometry is linear; sp hybridisation with bond angle of 180°.
