The `EN's` of `F, CI` Br and I are 4.0 ,3.0, 2.8 and 2.5 respectively The hybrogen halide with a highest percentage of ionic character is .

A

`HI`

B

`HBr`

C

`HCI`

D

`HF`

Text Solution

Verified by Experts

The correct Answer is:
D
Greater the `EN` difference between `H` and `X` in `HX` more ionic the compound
`EN` of `H=2.1` Therefore `EN` differnce in `HX` is
`{:(H-F=4.0-2.1=1.9,,,,),(H-CI=3.0-2.1=0.9,,,,),(H-Br=2.8-2.1=0.7,,,,),(H-I=2.5-2.1=0.4,,,,):}` .
