Question

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:

Options

• (A), (B), (C) only

• (B), (C), (E) only

• (A), (C) only

• (D) only

Answer 1

(A), (C) only

Explanation:

Bond strength `∝` Bond order

Removal of the electron from antibonding MO increases bond order.

NO and O₂ have valence e⁻ in π* orbital.
