The hydrolysis of 2-bromo-3-methyl butane by \[{{S}_{N}}1\]mechanism gives mainly

A)  3-methl-2-butanol

B)  2-methyl-2-butanol

C)  2,2-dimethyl-l-propanol

D)  2 methyl- 1-butanol

Correct Answer: C

Solution :

 \[C{{H}_{3}}-\underset{Br}{\mathop{\underset{|}{\mathop{C}}\,}}\,H-\underset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{C}}\,}}\,-C{{H}_{3}}\xrightarrow[-HBr]{{{H}^{+}}}\]
