    In the esterification of alcohol, the order of reactivity is

    A)  \[2{}^\circ >3{}^\circ >1{}^\circ \]

    B)  \[3{}^\circ >2{}^\circ >1{}^\circ \]

    C)  \[1{}^\circ >2{}^\circ >3{}^\circ \]

    D)  \[1{}^\circ >2{}^\circ >3{}^\circ \]

    Correct Answer: C

    Solution :

     In esterification alcohol acts as acid. Order of acidity and esterification of alcohol is as \[1{}^\circ >2{}^\circ >3{}^\circ \] Example? \[\underset{\begin{smallmatrix}  carboxylic \\  acid \end{smallmatrix}}{\mathop{RCOOH}}\,+\underset{alcohol}{\mathop{HOR}}\,\xrightarrow[-{{H}_{2}}O]{Esterification}\underset{ester}{\mathop{R-COOR}}\,\]
