Question

The bond orders in the pairs of bonded oxygen atoms in ozone molecules are:

• A. $(1,2)$
• B. $(\frac{1}{2},1\frac{1}{2})$
• C. $(1\frac{1}{2},1\frac{1}{2})$
• D. $(\frac{1}{2},2\frac{1}{2})$

Answer 1

The correct option is C $(1\frac{1}{2},1\frac{1}{2})$

The bond orders in the pairs of bonded oxygen atoms in ozone molecules are $(1\frac{1}{2},1\frac{1}{2})$. There are 2 O-O single bonds and one O=O double bond between 3 O atom. Hence, for each O atom, the bond order is $\frac{1+2}{2}=1.5$
