In the following sequence of reactions, the compound C formed would be \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  N{{H}_{2}} \end{smallmatrix}}{\mathop{CH}}\,-C{{H}_{3}}\xrightarrow[{}]{HN{{O}_{2}}}A\xrightarrow[{}]{OX}B\] \[\xrightarrow[{{H}^{+}}/{{H}_{2}}O]{C{{H}_{3}}MgI}C\]

A)  butanol - 1

B)  butanol - 2

C)  2 - methylpropanol - 2

D)  1,1 - Dimethylethanol

Correct Answer: C

Solution :

: \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  N{{H}_{2}} \end{smallmatrix}}{\mathop{CH}}\,-C{{H}_{3}}+HN{{O}_{2}}\xrightarrow[{}]{{}}\] \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\mathop{CH}}\,-C{{H}_{3}}+{{N}_{2}}+{{H}_{2}}O\]
