  • question_answer
    Which equilibrium can be described as an acid-base reaction using the Lewis acid-base definition but not using the Bronsted-Lowry definition           [AIIMS 1980]

    A)                 \[2N{{H}_{3}}+{{H}_{2}}S{{O}_{4}}\]⇄ \[2NH_{4}^{+}+SO_{4}^{2-}\]

    B)                 \[N{{H}_{3}}+C{{H}_{3}}COOH\]⇄ \[NH_{4}^{+}+C{{H}_{3}}CO{{O}^{-}}\]

    C)                 \[{{H}_{2}}O+C{{H}_{3}}COOH\]⇄ \[{{H}_{3}}{{O}^{+}}+C{{H}_{3}}CO{{O}^{-}}\]

    D)                 \[{{[Cu{{({{H}_{2}}O)}_{4}}]}^{2+}}+4N{{H}_{3}}\]⇄ \[{{[Cu{{(N{{H}_{3}})}_{4}}]}^{2+}}+4{{H}_{2}}O\]

    Correct Answer: D

    Solution :

                    It involves gain and loss of electron pair (Lewis concept).
