Question

Mark the incorrect statement in the following. (A) The bond order in the species O2 ,O2+ and O2- decreases as O2+ > O2 > O2- (B) The bond energy in a diatomic molecule always increases when an electron is lost (C) Electrons in antibonding MO contribute to repulsion between two atoms (D) With increase in bond order, bond length decreases and bond strength increases

Tardigrade Admin · Accepted Answer

When a diatomic molecule lost electron, then its bond order may increase or decrease, so its bond energy may decrease or increase.

Q. Mark the incorrect statement in the following.

The bond order in the species $O_{2}, O_{2}^{+}$ and $O_{2}^{-}$ decreases as $O_{2}^{+} > O_{2} > O_{2}^{-}$

The bond energy in a diatomic molecule always increases when an electron is lost

Electrons in antibonding $MO$ contribute to repulsion between two atoms

With increase in bond order, bond length decreases and bond strength increases

When a diatomic molecule lost electron, then its bond order may increase or decrease, so its bond energy may decrease or increase.
