According to MO theory, number of species/ions from the following having identical bond order is ________.
$$\mathrm{CN}^{-}, \mathrm{NO}^{+}, \mathrm{O}_{2}, \mathrm{O}_{2}^{+}, \mathrm{O}_{2}^{2+}$$
Answer (integer)
3
Solution
$\mathrm{CN}^{-}, \mathrm{NO}^{+}$and $\mathrm{O}_{2}^{2+}$ have bond order of 3
<br/><br/>
$\mathrm{O}_{2}$ has bond order of 2
<br/><br/>
$\mathrm{O}_{2}^{+}$ has bond order of $2.5$
<br/><br/>
$\therefore 3$ species have similar bond order.
