    Which of the following is a strong base?

    A)  Benzamide      

    B)  Butanamine

    C)  Nitrobenzene    

    D)  Benzene

    Correct Answer: B

    Solution :

     Amines are basic in nature due to the presence of lone pair of electron. Hence, they can accept the proton. The basic nature of amine increases with the increasing of +7 (Inductive) effect. Butanamine has the tendency to accept the proton due to the presence of lone pair of electron on nitrogen atom hence, it is a strong base. \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}\overset{\bullet \,\bullet }{\mathop{N}}\,{{H}_{2}}\]
