Question

\text{The total number of molecules with zero dipole moment among CH}_4, \text{ BF}_3, \text{ H}_2\text{O, HF, NH}_3, \text{ CO}_2 \text{ and} \\\ \text{SO}_2 \text{ is \\_\\_\\_\\_\\_\\_\\_\\_.}

Answer 1

Molecules with zero dipole moment are $\text{CO}_2$, $\text{CH}_4$, and $\text{BF}_3$.

Thus, the total number of molecules with zero dipole moment is: 3.

The Correct Answer is: 3
