Current Question (ID: 8692)

Question:

$\text{A compound that has both polar and non-polar bonds is –}$

Options:

1. $\text{NH}_4\text{Cl}$
2. $\text{HCN}$
3. $\text{H}_2\text{O}_2$
4. $\text{CH}_4$

Solution:

$\text{Hint: Hydrogen peroxide contains both polar and nonpolar bond}$ $\text{NH}_4\text{Cl} \text{ contains only polar bonds because of the nitrogen and hydrogen electronegativity difference.}$ $\text{HCN contains only polar bonds due to the electronegativity difference between carbon and nitrogen.}$ $\text{CH}_4 \text{ only contains a non-polar bond because the electronegativity difference between carbon and hydrogen is not much.}$ $\text{The structure of } \text{H}_2\text{O}_2 \text{ is as follows:}$ $\text{H-O-O-H}$ $\text{The O-H bond is polar because oxygen is more electronegative than hydrogen but O-O bond is non-polar. Hence, option third is the correct answer.}$ $\text{Therefore, } \text{H}_2\text{O}_2 \text{ is the only compound among the given options that contains both polar } (\text{O-H}) \text{ and non-polar } (\text{O-O}) \text{ bonds.}$
