  • question_answer Which of the following has a bond order of 1.75?

    A)  \[ClO_{3}^{-}\]           

    B)  \[ClO_{4}^{-}\]

    C)  \[NO_{3}^{-}\]          

    D)  \[CO_{3}^{2-}\]

    Correct Answer: B

    Solution :

     The resonating structures of\[ClO_{4}^{-}\]are as Bond order \[=\frac{total\text{ }number\text{ }of\text{ }bonds\text{ }between\text{ }Cl\text{ }and\text{ O}}{total\text{ }number\text{ }of\text{ }resonating\text{ }structures}\] \[=\frac{7}{4}=1.75\]
