    \[{{C}_{2}}{{H}_{5}}Br+C{{H}_{3}}CHO\xrightarrow{{}}X\xrightarrow{H.OH}\]Y, product Y is :

    A)  propanol      

    B)                         2-butanol

    C)                         both (a) and (c)

    D)                         none of these

    Correct Answer: B

    Solution :

    \[C{{H}_{3}}-\underset{O}{\mathop{\underset{||}{\mathop{C}}\,}}\,-H+{{C}_{2}}{{H}_{5}}MgBr\xrightarrow{{}}\] \[C{{H}_{3}}-\underset{{{C}_{2}}{{H}_{5}}}{\mathop{\underset{|}{\mathop{\overset{H}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-OMgBr\xrightarrow{H.OH}\] \[\underset{2-\text{butanol}}{\mathop{C{{H}_{3}}-\underset{{{C}_{2}}{{H}_{5}}}{\mathop{\underset{|}{\mathop{C}}\,}}\,HOH+Mg(OH)Br}}\,\]
