    Which of the following statements is correct?

    A) \[s{{p}^{3}}-\] hybrid orbitals have equal s and p character   

    B)  The bond angle decreases with the decrease of s character of a hybridized orbital

    C)  Resonance decreases the stability of a molecule

    D)  Resonance is due to delocalization of sigma electrons

    Correct Answer: B

    Solution :

     The bond angle decreases with the decrease of s-character of hybridized orbital.
    Hybridization \[\text{s}{{\text{p}}^{3}}\] \[\text{s}{{\text{p}}^{2}}\] \[\text{sp}\]
    Bond angle \[\text{10}{{\text{9}}^{o}}28'\] \[{{120}^{o}}\] \[{{180}^{o}}\]
