    Propan-2-ol + ethanoic acid\[\xrightarrow{{}}\]

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

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

    C)  \[C{{H}_{3}}COOC{{H}_{2}}C{{H}_{3}}\]

    D)  \[{{(C{{H}_{3}})}_{2}}CHCOOC{{H}_{2}}C{{H}_{3}}\]

    Correct Answer: B

    Solution :

     \[\underset{ethanoic\,acid}{\mathop{C{{H}_{3}}COOH}}\,+\underset{propan-2-ol}{\mathop{HOCH{{(C{{H}_{3}})}_{2}}}}\,\] \[\xrightarrow{{{H}_{2}}S{{O}_{4}}}\underset{\text{iso}-\text{propyl}\,\text{ethanoate}}{\mathop{C{{H}_{3}}COOCH{{(C{{H}_{3}})}_{2}}}}\,\] This reaction is called esterification as ester is the final product.
