Identify the molecule that has zero dipole moment.

A) \[C{{H}_{3}}Cl\]               

B) \[CHC{{l}_{3}}\]

C) \[C{{H}_{2}}C{{l}_{2}}\]                

D) \[CC{{l}_{4}}\]

Correct Answer: D

Solution :

                \[CC{{l}_{4}},\]because of its symmetrical structure, has zero dipole moment. [Here, two dipoles vanish the effect of other two dipoles, thus the resultant dipole moment is zero.]
