What is the total number of electrons present in bonding orbitals of O ₂ molecule according to molecular orbital theory?

Options

  1. A16
  2. B06
  3. C10
  4. D04

Correct answer

C. 10

Step-by-step solution

The electronic configuration of O ₂ molecule is ( 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 . Bonding molecular orbitals contain 10 electrons.
