    Compounds X and Z in the following reaction are-\[C{{H}_{3}}CHO\xrightarrow[(ii)\,\,{{H}_{2}}O]{(i)\,\,C{{H}_{3}}MgBr}(X)\xrightarrow{{{H}_{2}}S{{O}_{4}},\,\Delta }(Y)\]\[\xrightarrow{Hydroboration\,\,oxidation}(Z)\]

    A) Identical

    B) Positional isomers

    C) Functional isomers

    D) Optical isomers

    Correct Answer: B

    Solution :

    [B] \[X=C{{H}_{3}}-CH(OH)-C{{H}_{3}}\] \[Y=C{{H}_{3}}-CH=C{{H}_{2}}\] \[Z=C{{H}_{3}}-C{{H}_{2}}-C{{H}_{3}}OH\]
