    The main product of the reaction would be 2-butene + chloroform\[\,\xrightarrow{\text{NaOH}}\]?

    A)  butanoic acid 

    B)  2-methyl butanoic acid

    C)  \[1,1,1-\]trichloro\[-2-\]methyl butane

    D)  \[1.4-\]butanediol

    Correct Answer: B

    Solution :

     \[C{{H}_{3}}CH=CH-C{{H}_{3}}+CHC{{l}_{3}}\xrightarrow{{}}\] \[C{{H}_{3}}-\overset{CC{{l}_{3}}}{\mathop{\overset{|}{\mathop{CH}}\,}}\,-C{{H}_{2}}-C{{H}_{3}}\xrightarrow[\text{hydrol}]{\text{NaOH}}\] \[C{{H}_{3}}-\overset{C(OH)3}{\mathop{\overset{|}{\mathop{CH}}\,}}\,-C{{H}_{2}}-C{{H}_{3}}\xrightarrow[{}]{-{{H}_{2}}O}\] \[\underset{2-\text{methyl}\,\text{butanoic}\,\text{acid}}{\mathop{C{{H}_{3}}-\overset{COOH}{\mathop{\overset{|}{\mathop{CH}}\,}}\,-C{{H}_{2}}C{{H}_{3}}}}\,\]
