    Which of the following trihalides of P has maximum bond angle?

    A)  \[P{{F}_{3}}\]             

    B)  \[PB{{r}_{3}}\]

    C)  \[PC{{l}_{3}}\]            

    D)  \[P{{I}_{3}}\]

    Correct Answer: D

    Solution :

     As the electronegativity of X in\[P{{X}_{3}}\]decreases, the bonding pair of electrons will be more close to the central atom and bond pair-bond pair repulsion increases which results in increase in bond angle. Hence,\[P{{I}_{3}}\]as maximum bond angle.
