  • question_answer
    Which one of the following compounds will react with \[NaHC{{O}_{3}}\] solution to give sodium salt and carbon dioxide?                                  [AIPMT 1999]

    A) Acetic acid

    B) n-hexanol

    C) Phenol

    D) Both [b] and [c]

    Correct Answer: A

    Solution :

    [a] Only acetic acid reacts with \[NaHC{{O}_{3}}\] to give sodium salt and \[C{{O}_{2}},\] because \[NaHC{{O}_{3}}\] is a base and it reacts with acid only.
                This is one of the distinguishing test of carboxylic acids.
    \[R-COOH+NaHC{{O}_{3}}\to R-COONa+C{{O}_{2}}\]\[+{{H}_{2}}O\]
