The major product of the following reaction is \[C{{H}_{3}}-\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{\underset{OH}{\mathop{\underset{|}{\mathop{C}}\,}}\,}}\,}}\,-C{{H}_{2}}-OH\xrightarrow{{{H}_{2}}S{{O}_{4}}}\]

A)  \[{{(C{{H}_{3}})}_{2}}C=C{{H}_{2}}\]

B)  butan-2-one

C)  \[{{(C{{H}_{3}})}_{2}}\overset{OH}{\mathop{\overset{|}{\mathop{C}}\,}}\,=CHO\]

D)  isobutyraldehyde

Correct Answer: D

Solution :

\[C{{H}_{3}}-\overset{C{{H}_{3}}}{\mathop{\underset{OH}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}\,}}\,-C{{H}_{2}}-OH\xrightarrow{{{H}^{+}}}\]
