Which of the following molecule has bond order 2?

Options

  1. AN ₂
  2. BH ₂
  3. CO ₂
  4. DF ₂

Correct answer

C. O ₂

Step-by-step solution

The electronic configuration of O ₂ molecule is aligned & ( 1 ~s )^2 ( ^* 1 ~s )^2( 2 ~s )^2 ( ^* 2 ~s )^2 ( 2 p _ z )^2 ( 2 p _ x )^2 & ( 2 p _ y )^2 ( ^* 2 p _ x )^1 ( ^* 2 p _ y )^1 aligned Bond order of O ₂ molecule = N _ b - N _ a 2 = 10-6 2 =2
