\[C{{H}_{3}}\text{ }CHO+C{{H}_{3}}\text{ }Mg\text{ }Br\xrightarrow{{}}\text{ }X\]compound X is:

A)  a secondary alcohol

B)  a tertiary alcohol

C)  a primary alcohol

D)  \[C{{H}_{3}}-C-C{{H}_{3}}\]

Correct Answer: A

Solution :

\[C{{H}_{3}}CHO+C{{H}_{3}}MgBr\xrightarrow{{}}\] \[C{{H}_{3}}-\underset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{\overset{H}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-OMgBr\xrightarrow{H.\,OH/{{H}^{+}}}\]
