The molecule (ion) having one unpaired electron is

Options

  1. ANO
  2. BCO
  3. CCN ⁻
  4. DO ₂

Correct answer

A. NO

Step-by-step solution

Nitric oxide (NO) has one unpaired electron and it is paramagnetic in nature. It has 15 electrons. aligned & NO : K K (2 s)^2 * (2 s)^2 (2 p_z )^2 (2 p_x )^2 (2 p_y )^2+ (2 p_x )^1 aligned
