Question

Which of the following contains both polar and non-polar bonds?

• A. $N{H}_{4}Cl$
• B. $HCN$
• C. $H_2{O}_2$
• D. $C{H}_4$

Answer 1

Answer: (C)

$H_2{O}_2$

The sulphur atom in sulphur dioxide is $s{p}^2$-hybridization, and it is a V-shaped molecule.

In $N{H}_{4}Cl$, all the bonds are polar.

In $HCN$, the bonds are polar.

In hydrogen peroxide, $O-O$ bond is non-polar and $O-H$ bonds are polar.

In $C{H}_4$, all the four bonds are non-polar.

Therefore, the correct option is C.
