    Among the following, the molecule with the lowest dipole moment is     JEE Main  Online Paper (Held On 19  May  2012)

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

    B)                        \[C{{H}_{3}}Cl\]

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

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

    Correct Answer: D

    Solution :

                    \[CC{{l}_{4}}\] has lowest (zero) dipole moment. This is due to its symmetrical tetrahedral structure. Due to which dipole moment of one bond is cancelled by opposite dipole moment of the other three bonds.
