    Which of the following would be expected to be most highly ionised in water                                     [AIIMS 1982]

    A)                 \[C{{H}_{2}}ClC{{H}_{2}}C{{H}_{2}}COOH\]          

    B)                 \[C{{H}_{3}}CHCl.C{{H}_{2}}.COOH\]

    C)                 \[C{{H}_{3}}.C{{H}_{2}}.CC{{l}_{2}}.COOH\]         

    D)                 \[C{{H}_{3}}.C{{H}_{2}}.CHCl.COOH\]

    Correct Answer: C

    Solution :

                    \[C{{H}_{3}}-C{{H}_{2}}-CC{{l}_{2}}-COOH\]; a,a-dichloro butanoic acid is most acidic. Hence it will easily loose \[{{H}^{+}}\] ions in solution.
