Which one of the following orders is not in accordances with the property stated against it?

Options

(a) F₂ > Cl₂ > Br₂ > I₂ : Oxidising power
(b) HI > HBr > HCl > HF : Acidic property in water
(c) F₂ > Cl₂ > Br₂ > I₂ : Electronegetivity
(d) F₂ > Cl₂ > Br₂ > I₂ : Bond dissociation energy

Correct Answer:

F₂ > Cl₂ > Br₂ > I₂ : Bond dissociation energy

Explanation:

The correct order of bond disassociation is Cl₂>Br₂>F₂>I₂ Generally this energy decreases as the bond length increases; but this energy of F₂ is less than Cl₂ and Br₂ because of its greater interelecreonics repulsions (due to its small size).
