Question

Which of the following molecules has polar bonds but is a nonpolar molecule?

• A. $H_2$
• B. $H_{2}O$
• C. $N{H}_3$
• D. $NaCl$
• E. $C{O}_2$

Answer 1

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

Carbon dioxide $C{O}_2$ has polar bonds but is a nonpolar molecule. The structure of $C{O}_2$ is linear. The individual bond dipoles cancel each other as they point in opposite direction and are equal in magnitude. Hence, the molecule is non polar with zero dipole moment.
