    Which of the following have asymmetric carbon atom? (1)\[C{{H}_{2}}ClC{{H}_{2}}Br\] (2)\[C{{H}_{3}}CHDCl\] (3)\[C{{H}_{3}}CHC{{l}_{2}}\] (4)\[C{{H}_{2}}BrCHOHC{{H}_{3}}\]

    A)  1, 2 and 3 are correct

    B)  1 and 2 are correct

    C)  2 and 4 are correct

    D)  1 and 3 are correct

    Correct Answer: C

    Solution :

                     \[Cl-\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix}  D \\  | \end{smallmatrix}}{\mathop{{{C}^{*}}}}}\,-H\,C{{H}_{2}}Br-\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\overset{\begin{smallmatrix}  H \\  | \end{smallmatrix}}{\mathop{{{C}^{*}}}}}\,-C{{H}_{3}}\]where\[{{C}^{*}}=\]asymmetric carbon atom
