• question_answer Among the following compounds which can be dehydrated very easily is [AIEEE 2004] A) $C{{H}_{3}}-C{{H}_{2}}-\underset{OH\ \ \ \ \ \ }{\overset{C{{H}_{3}}\ \ \ \ }{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,-C{{H}_{2}}}}}\,-C{{H}_{3}}$ B) $C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-\overset{OH}{\mathop{\overset{|}{\mathop{C}}\,H}}\,-C{{H}_{3}}$ C) $C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-C{{H}_{2}}-C{{H}_{2}}-OH$ D) $C{{H}_{3}}-C{{H}_{2}}-\underset{C{{H}_{3}}\ }{\mathop{\underset{|}{\mathop{C}}\,H-}}\,C{{H}_{2}}-C{{H}_{2}}-OH$

$C{{H}_{3}}-C{{H}_{2}}-\underset{OH\ \ \ \ \ \ \ }{\overset{C{{H}_{3}}\ \ \ \ \ }{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,-C{{H}_{2}}}}}\,-C{{H}_{3}}\xrightarrow{{{H}^{+}}}$$C{{H}_{3}}-C{{H}_{2}}-\overset{C{{H}_{3}}\ \ \ \ \,}{\mathop{\underset{\oplus }{\overset{|}{\mathop{C}}}\,-C{{H}_{2}}}}\,-C{{H}_{3}}$ The more stable carbocation is generated thus more easily it will be dehydrated.
