  • question_answer
    Nitrobenzene can be prepared from benzene by using a mixture of cone \[HN{{O}_{3}}\], and cone. \[{{L}^{-1}}{{s}^{-1}},\]In the mixture, nitric acid acts as a/an:

    A) reducing agent

    B) acid                       

    C)        base                     

    D)        catalyst

    Correct Answer: C

    Solution :

    Key Idea Proton donor are acids and proton acceptor are bases. Cone. \[Co{{(N{{H}_{3}})}_{5}}(N{{O}_{2}})Cl\] and cone. \[({{k}_{f}}=-{{1.86}^{o}}C/m)\] react in the following manner: \[C{{H}_{3}}OH\] \[C{{H}_{3}}Cl\] Hence, in this reaction \[AlC{{l}_{3}}\]acts as a base and \[n=4,l=0,m=0,s=-1/2\]as an acid.
