      From amongst the following alcohols the one that would react fastest with conc,\[HCl\]and anhydrous\[ZNC{{l}_{2}},\]is       AIEEE  Solved  Paper-2010

    A) 1- Butanol          

    B)        2- Butanol

    C) 2- Methylpropan -2-ol

    D) 2- Methylpropanol

    Correct Answer: C

    Solution :

    Reactivity of\[LuCaS\]reagent for alcohol \[=3{}^\circ >2{}^\circ >1{}^\circ >C{{H}_{3}}\] \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\overset{\begin{smallmatrix}  \,\,\,\,C{{H}_{3}} \\  | \end{smallmatrix}}{\mathop{C}}}\,-C{{H}_{3}}\] 2-methyl. 2-propanol (\[3{}^\circ \]-alcohol) highest reactivity
