MCQ

Which one of the following shows optical activity

A
$HO - \mathop {\mathop {\mathop {\mathop C\limits^| }\limits^H }\limits_| }\limits_H - COOH$
✓
$C{H_3} - \mathop {\mathop {\mathop {\mathop C\limits^| }\limits^H }\limits_| }\limits_{Cl} - COOH$
C
$C{H_3} - \mathop {\mathop {\mathop {\mathop {C - \,}\limits^{|\,\,\,\,\,} }\limits^{C{H_3}} }\limits_{|\,\,\,\,\,\,} }\limits_{OH\,\,} COOH$
D
$C{H_3} - \mathop {\mathop {\mathop {\mathop {C - \,}\limits^{|\,\,\,\,\,\,} }\limits^{C{H_3}} }\limits_{|\,\,\,\,\,\,} }\limits_{Cl\,\,\,} COOH$

✓

Answer

Correct option: B.

$C{H_3} - \mathop {\mathop {\mathop {\mathop C\limits^| }\limits^H }\limits_| }\limits_{Cl} - COOH$

b
(b) $C{H_3} - \mathop {\mathop {\mathop {\mathop C\limits_| }\limits_{Cl} \,}\limits^{|*} }\limits^H - COOH$

In this structure chiral carbon atom is present since it is optical active.
