Medium MCQ +4 / -1 PYQ · JEE Mains 2022

Bonding in which of the following diatomic molecule(s) become(s) stronger, on the basis of MO Theory, by removal of an electron?

(A) NO

(B) N2

(C) O2

(D) C2

(E) B2

Choose the most appropriate answer from the options given below :

  1. A (A), (B), (C) only
  2. B (B), (C), (E) only
  3. C (A), (C) only Correct answer
  4. D (D) only

Solution

If an electron is removed from the anti-bonding orbital, then it will tend to increase the bond order. The HOMO in NO and O<sub>2</sub> is antibonding molecular orbital .<br/><br/> Hence, in NO and O<sub>2</sub> bond order will increase on loss of electron.
