Question

The $Cl-O$ bond order in the perchlorate ion ($ClO_4^-$) is calculated as $x.xx$. What is the value of $x.xx \times 100$?

Answer: 175

💡 Solution & Explanation

In the perchlorate ion, the central chlorine atom forms three double bonds and one single bond, creating 7 total bonds resonating across 4 oxygen atoms. $B.O. = \frac{7}{4} = 1.75$. Multiplying by 100 yields 175.
