  • question_answer
    Chloroform can be obtained from [MNR 1986]

    A) Methanol

    B) Methanal

    C) Propanol-1

    D) Propanol-2

    Correct Answer: D

    Solution :

               \[CaOC{{l}_{2}}+{{H}_{2}}O\to Ca{{(OH)}_{2}}+C{{l}_{2}}\]                    \[\underset{\text{2-propanol}}{\mathop{C{{H}_{3}}-\underset{\underset{OH}{\mathop{|\,\,\,\,}}\,}{\mathop{CH}}\,-C{{H}_{3}}+C{{l}_{2}}}}\,\to \]\[C{{H}_{3}}-\underset{\underset{O}{\mathop{||}}\,}{\mathop{C}}\,-C{{H}_{3}}+2HCl\]            \[C{{H}_{3}}-\underset{\underset{O}{\mathop{||}}\,}{\mathop{C\,}}\,-C{{H}_{3}}+3C{{l}_{2}}\to CC{{l}_{3}}-CO-C{{H}_{3}}+3HCl\] \[\begin{matrix}    CC{{l}_{3}}COC{{H}_{3}}  \\    CC{{l}_{3}}COC{{H}_{3}}  \\ \end{matrix}+Ca<\begin{matrix}    OH  \\    OH  \\ \end{matrix}\to 2CHC{{l}_{3}}+\begin{matrix}    C{{H}_{3}}COO  \\    C{{H}_{3}}COO  \\ \end{matrix}>Ca\]
