MCQ
The maximum number of stereoisomers possible for 2-hydroxy- 2-methyl butanoic acid is
- A$1$
- ✓$2$
- C$3$
- D$4$
✓
Answer
Correct option: B.
$2$
b
(b) $COOH - \mathop {\mathop {{C^ * }\, - \,}\limits_{|\,\,\,\,\,\,\,}^{|\,\,\,\,\,\,\,\,} }\limits_{OH\,}^{C{H_3}} C{H_2} - C{H_3}$
(b) $COOH - \mathop {\mathop {{C^ * }\, - \,}\limits_{|\,\,\,\,\,\,\,}^{|\,\,\,\,\,\,\,\,} }\limits_{OH\,}^{C{H_3}} C{H_2} - C{H_3}$
One chiral centre. Therefore two forms are possible.
