\[C{{H}_{3}}MgBr+A\xrightarrow{{}}B\xrightarrow{{{H}_{2}}O/{{H}^{+}}}\] \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}OH\] In the above reaction sequence A is:

A)  \[C{{H}_{3}}CHO\]

B)                         \[{{(C{{H}_{3}})}_{2}}CO\]

C)                         \[{{(C{{H}_{2}})}_{2}}O\]

D)                         \[C{{H}_{3}}C{{H}_{2}}CHO\]

Correct Answer: C

Solution :

                \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}-OMgBr\xrightarrow{H.OH}\]                 \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}OH+Mg(OH)Br\]
