- B$HCl$
- C$HN{O_3}$
- D${H_2}S{O_4}$
✓
Answer
Correct option: A.
$HF$
(a) We know that greater the difference in electronegativity of two atoms forming a covalent bond. More is its polar nature.
In $HF$ there is a much difference in the electronegatives of hydrogen and flourine. Therefore $(HF)$ is a polar compound.
