    Among the following molecules which one have smallest bond angle      [Orissa JEE 2005]

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

    B)                 \[P{{H}_{3}}\]

    C)                 \[{{H}_{2}}O\]  

    D)                 \[{{H}_{2}}Sc\]

    E)                 \[{{H}_{2}}S\]                   

    Correct Answer: D

    Solution :

               \[N{{H}_{3}}=107{}^\circ ,\ P{{H}_{3}}=93{}^\circ ,\ {{H}_{2}}O=104.5{}^\circ \]                                 \[{{H}_{2}}Se=91{}^\circ ,\ {{H}_{2}}S=92.5{}^\circ \]
