    In the series ethane, ethylene and acetylene, the \[C-H\]  bond energy is                                            [NCERT 1977]

    A)                 The same in all the three compounds

    B)                 Greatest in ethane

    C)                 Greatest in ethylene

    D)                 Greatest in acetylene

    Correct Answer: D

    Solution :

                    As the bond order increases, \[C-H\] bond energy also increases so it will be greatest in acetylene because its B.O. is 3.
