    Arrange the following bonds according to their average bond energies in descending order \[C-Cl,C-Br,C-F,C-l\] [JEE MAIN Held on 08-01-2020 Evening]

    A) \[C-Cl>C-Br>C-l>C-F\]

    B) \[C-Br>C-l>C-Cl>C-F\]

    C) \[C-F>C-Cl>C-Br>C-l\]

    D) \[C-l>C-Br>C-Cl>C-F\]

    Correct Answer: C

    Solution :

    Generally, bond energy \[\alpha \,\,\,\frac{1}{bond\,\,length}\] So bond energy order is \[C-F>C-Cl>C-Br>C-l\]
