Between HF, HCl, HBr and HI, HF has the highest ionic character because

A

F has the highest electron affinity

B

In HF , electronegativity difference is highest

C

`F^(-)` ion has the highest value of ionic radius

D

Atomic orbitals of H and F have almost similar energy

Text Solution

Verified by Experts

The correct Answer is:
B
HF has the highest electronegativity difference because electronegativity of halogen follow the order `F gt CL gt Br gt I`
