    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 :

     \[\text{CC}{{\text{l}}_{\text{4}}}\text{,}\] 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.]
