    As the 5-character of hybridisation orbital increases, the bond angle

    A)  increases

    B)  decreases

    C)  first increases then decreases

    D)  does not change

    Correct Answer: A

    Solution :

                    s-character increases with increase in bond angle.
    Hybridisation % of s-character Bond angle
    \[sp\] \[50\] \[{{180}^{o}}\]
    \[s{{p}^{2}}\] \[33.3\] \[{{120}^{o}}\]
    \[s{{p}^{3}}\] \[25\] \[{{109}^{o}}28\]
