Carbon tetrachloride has no dipole moment, because

Options

A. similar sizes of carbon and chlorine atoms
B. it is symmetrical tetrahedral structure
C. it is planar structure
D. none of the above.

Answer

B

Explanation

Due to symmetrical tetrahedral structure, the dipole moment of one C-Cl bond in `C Cl_4` is cancelled by opposite C-Cl bond. Thus a molecule has polar bonds but zero dipole moment.
