Which one of the following orders is not correct in accordance with the property stated against is ?

Options

A. `F_(2) gt Cl_(2) gt Br_(2) gt I_(2)`: Bond dissociation energy
B. `F_(2) gt Cl_(2) gt Br_(2) gt I_(2)`: Oxidising power
C. `HI gt HBr gt HCl gt HF`: Acidic property in water
D. `F_(2) gt Cl_(2) gt Br gt I_(2)`: Electronegativity

Answer

1

Explanation

The correct order of bond dissociation energy is
`Cl_(2) gt Br_(2) gt F_(2) gt I_(2)`
The low bond dissociation energy of `:underset(..)overset(..)(F)-underset(..)overset(..)(F):` bond is due to repulsion between the lone pairs on small F atoms.
