    Which one of the following compounds has the smallest bond angle in its molecule?     AIEEE  Solved  Paper-2003

    A) \[S{{O}_{2}}\]                                   

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

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

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

    Correct Answer: C

    Solution :

    Molecule Hybridisation Repulsion Bond angle
    \[S{{O}_{2}}\] \[s{{p}^{2}}\] \[lp-bp,bp-bp\] \[{{119}^{o}}\]
    \[O{{H}_{2}}\] \[s{{p}^{3}}\] \[lp-lp,bp-lp\] \[{{104.5}^{o}}\]
    \[S{{H}_{2}}\] \[s{{p}^{3}}\] -do- \[{{90}^{o}}\]
    \[N{{H}_{3}}\] \[s{{p}^{3}}\] \[lp-bp,\,bp-bp\] \[{{107}^{o}}\]
