    Which of the following shows optical isomerism?

    A)  \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  COOH \end{smallmatrix}}{\overset{\begin{smallmatrix}  Cl \\  | \end{smallmatrix}}{\mathop{C}}}\,-H\]

    B)  \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\overset{\begin{smallmatrix}  Cl \\  | \end{smallmatrix}}{\mathop{C}}}\,-COOH\]

    C)  \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  COOH \end{smallmatrix}}{\overset{\begin{smallmatrix}  COOH \\  | \end{smallmatrix}}{\mathop{C}}}\,-H\]

    D)  \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  COOH \end{smallmatrix}}{\overset{\begin{smallmatrix}  COOH \\  | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{3}}\]

    Correct Answer: A

    Solution :

     \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  COOH \end{smallmatrix}}{\overset{\begin{smallmatrix}  Cl \\  | \end{smallmatrix}}{\mathop{{{C}^{*}}}}}\,-H\]shows optical isomerism because it contains asymmetrical carbon atom (C*)
