- A$NH_4Cl$
- B$HCN$
- ✓$H_2O_2$
- D$CH_4$
✓
Answer
Correct option: C.
$H_2O_2$
c
Polarity is resulting from unequal sharing of electrons. There are three sigma bonds present in hydrogen peroxide. Two of them are between hydrogen and oxygen atoms which is polar in nature. The other one is between two oxygen atoms where there is no unequal sharing of electrons as they have same dipole moment. So it is non polar. So the correct answer is hydrogen peroxide.
