    In which of the following, the bond length between hybridized carbon atom and other carbon atom is minimum?

    A)  Propyne

    B)                                         Propene            

    C)         Butane               

    D)         Propane

    Correct Answer: A

    Solution :

    We know that the C-C bond length \[\text{=1}\text{.54}\,\text{A,}\,\text{C}\,\,\text{= C}\]bond length = 1.34 A and \[\text{C}\equiv \text{C}\]bond length =1.20 A. Since propyne has tripel bond; therefore, it has minimum bond length.
