Question

Carbon tetrachloride has no net dipole moment because of :

• A. its planar structure.
• B. its regular tetrahedral structure.
• C. similar sizes of carbon and chlorine atoms.
• D. similar electron affinities of carbon and chlorine.

Answer 1

The correct option is B its regular tetrahedral structure.

Carbon tetrachloride is non polar molecule because the central carbon atom undergoes $s{p}^3$ hybridization which results in regular tetrahedral geometry in which all the four $C-Cl$ bond dipoles cancel each other. Hence, the molecule has no net dipole moment.
