    Among the trihalides of nitrogen which one of most basic in nature?

    A)  \[N{{F}_{3}}\]                     

    B)  \[NC{{l}_{3}}\]

    C)  \[N{{I}_{3}}\]    

    D)  \[NB{{r}_{3}}\]

    Correct Answer: C

    Solution :

    Since the electronegativity of X in \[\overset{\bullet \bullet }{\mathop{N}}\,{{X}_{3}}\] decreases from F to I hence, the tendency of N to donate its lone pair of electrons increases and therefore \[N{{I}_{3}}\] is the most basic trihalide of nitrogen.
