    Bond angle between two hybrid orbitals is \[{{105}^{o}}.%\] s-orbital character of hybrid orbital is                 [MP PMT 1986]

    A)                 Between \[20-21%\]     

    B)                 Between \[19-20%\]

    C)                 Between \[21-22%\]     

    D)                 Between \[22-23%\]

    Correct Answer: D

    Solution :

                    Bond angle between two hybrid orbitals is \[{{105}^{o}}\]it means orbitals are \[s{{p}^{3}}\] hybridised but to lone pair repulsion bond angle get changed from \[{{109}^{o}}\] to \[{{105}^{o}}\]. So its % of s-character is between 22-23%.
