      Column - I   Column - II
    a. Hexane 1. \[{{C}_{4}}{{H}_{10}}\]
    b. Ethane 2. \[{{C}_{6}}{{H}_{12}}\]
    c. Pentene 3. \[{{C}_{5}}{{H}_{10}}\]
    d. Hexane 4. \[{{C}_{2}}{{H}_{6}}\]
    e. Butane 5. \[{{C}_{6}}{{H}_{14}}\]

    A) a-5, b-4, c-3, d-1, e-2

    B) a-3, b-4, c-2, d-5, e-1

    C) a-5, b-4, c-3, d-2, e-1

    D) a-5, b-2, c-1, d-4, e-3

    Correct Answer: C

    Solution :

    The general formula of: alkanes is \[{{C}_{n}}{{H}_{2n+2}}\] The formula of Hexane-\[{{C}_{6}}{{H}_{14}}\]Ethane- \[{{C}_{2}}{{H}_{6}}\] Butane\[{{C}_{4}}{{H}_{10}}\]. Alkenes have general formula \[{{C}_{n}}{{H}_{2n}}\] . The formula of Pentene is\[{{C}_{5}}{{H}_{10}}\] and Hexene is \[{{C}_{6}}{{H}_{12}}\]. a-5, b-4, c-3, d-2, e-1
