    \[Z\xrightarrow[{}]{PCl}X\xrightarrow[{}]{alc\,KOH}Y\xrightarrow[{}]{conc\,{{H}_{2}}S{{O}_{4}}}Z\]Here Z is:

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

    B) \[{{(C{{H}_{3}})}_{2}}-C-OH\]

    C) \[C{{H}_{3}}-CH-C{{H}_{3}}\]

    D) none of above

    Correct Answer: C

    Solution :

     \[\underset{\begin{smallmatrix}  2-Propanol \\  \,\,\,\,\,\,\,\,\,(Z) \end{smallmatrix}}{\mathop{C{{H}_{3}}.\underset{\begin{smallmatrix}  | \\  OH \end{smallmatrix}}{\mathop{CH}}\,.C{{H}_{3}}}}\,\xrightarrow{PC{{l}_{5}}}\] \[\underset{\,\,(X)}{\mathop{C{{H}_{3}}.\underset{\begin{smallmatrix}  | \\  Cl \end{smallmatrix}}{\mathop{CH}}\,.C{{H}_{3}}}}\,\xrightarrow{alc.\text{ }KOH}\] \[\underset{\begin{smallmatrix}  1.propene \\  \,\,\,\,\,(Y) \end{smallmatrix}}{\mathop{C{{H}_{3}}.CH=C{{H}_{2}}}}\,\xrightarrow[{{H}_{2}}O/Heat]{Cone.{{H}_{2}}S{{O}_{4}}}Z\]
