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

Correct Answer: 3

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
