    A) 1 : 2                                      

    B) 2 : 1                                      

    C) 3 : 2                                      

    D) 2 : 3

    Correct Answer: B

    Solution :

    Propane \[({{C}_{3}}{{H}_{8}})=8H\] atoms and propyne  \[({{C}_{3}}{{H}_{4}})=4H\] atoms. Hence, the ratio = 8 : 4 = 2 : 1
