    As the \[p-\]character increases, the bond angle in hybrid orbitals formed by \[s\] and atomic orbitals [MP PMT 1997]

    A)                 Decreases          

    B)                 Increases

    C)                 Doubles              

    D)                 Remains unchanged

    Correct Answer: A

    Solution :

               As p-character increases the bond angle decreases.            In \[sp\] - p-character \[\frac{1}{2}\], bond angle - \[{{180}^{o}}\]            In \[s{{p}^{2}}\]- p-character \[\frac{2}{3}\], bond angle - \[{{120}^{o}}\]                 In \[s{{p}^{3}}\]- p-character \[\frac{3}{4}\], bond angle - \[{{109}^{o}}\]
