MCQ
Identify the non-polar molecule in the set of compounds given : $HCl,\,HF,\,{H_2},\,HBr$
- ✓${H_2}$
- B$HCl$
- C$HF,\,HBr$
- D$HBr$
✓
Answer
Correct option: A.
${H_2}$
(a) Polarity create due to the difference in electronegativity of both atom in a molecule except ${H_2}$ all other molecule have the different atom so they will have the polarity while ${H_2}$ will be non polar.
