MCQ
Which of the following is a polar compound
- ✓$HCl$
- B${H_2}Se$
- C$C{H_4}$
- D$HI$
✓
Answer
Correct option: A.
$HCl$
(a) Higher is the difference in electronegativity of two covalently bonded atoms, higher is the polarity. In $HCl$ there is high difference in the electronegativity of $H$ and $Cl$ atom so it is a polar compound.
