A) \[C{{H}_{3}}-CHOH-C{{H}_{2}}-C{{H}_{3}}\]
B) \[{{(C{{H}_{3}})}_{3}}-C-OH\]
C) \[C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-C{{H}_{2}}-OH\]
D) \[{{(C{{H}_{3}})}_{3}}-CH-C{{H}_{2}}OH\]
Correct Answer: B
Solution :
Tertiary alcohol readily reacts with halogen acid \[C{{H}_{3}}\to \underset{\underset{C{{H}_{3}}}{\mathop{\uparrow \,\,\,\,}}\,\,\,\,\,\,\,\,}{\mathop{\overset{\overset{C{{H}_{3}}}{\mathop{\downarrow \,\,\,\,}}\,\,\,\,\,\,\,\,}{\mathop{C-OH\,}}\,}}\,\to C{{H}_{3}}-\underset{\underset{C{{H}_{3}}}{\mathop{|\,\,\,\,\,\,\,\,}}\,\,\,\,\,\,\,\,\,\,\,}{\mathop{\overset{\overset{C{{H}_{3}}}{\mathop{|\,\,\,\,\,\,\,}}\,\,\,\,\,\,\,\,\,\,\,}{\mathop{{{C}^{+}}+O{{H}^{-}}}}\,}}\,\] Presence of 3 alkyl group increases electron density on \[{{3}^{o}}\]carbon atom. Hence \[-OH\] group is easily removed. After the removal of \[-OH\] group \[{{3}^{o}}\] carbonium ion is formed which is most stable
