Question

Which contains both polar and non-polar covalent bonds?

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

Answer 1

The correct option is C $H_2{O}_2$

$H_2{O}_2$ contains both polar and non-polar covalent bonds. In the structure of $H_2{O}_2$, there are 3 sigma bonds,2 between $O$ and $H$ and one bond is between 2 $O$ atoms.The two bonds between $O$ and $H$ are polar while that between two $O$ atoms are non-polar.
