    Which of the following will be chiral?

    A)  \[C{{H}_{3}}CHC{{l}_{2}}\]          

    B)  \[C{{H}_{3}}CHBrCl\]

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

    D)  \[C{{H}_{2}}ClBr\]

    Correct Answer: B

    Solution :

                    A carbon atom which is attached by four different group is called an asymmetric carbon atom or chiral centre. \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  Br \end{smallmatrix}}{\overset{\begin{smallmatrix}  H \\  | \end{smallmatrix}}{\mathop{{{C}^{*}}}}}\,-Cl\]
