MCQ

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

A
$F$ has the highest electron affinity
✓
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

✓

Answer

Correct option: B.

In $HF$, electronegativity difference is highest

b
Fluorine is most electronegative element. So, $HF$ has highest ionic character because electronegativity difference between $H$ and $F$ is highest.
