4.Chemical Bonding and Molecular Structure
medium
In which of the following pairs molecules have bond order three and are isoelectronics
A
$C{N^ - }$, $CO$
B
$N{O^ + },\,\,C{O^ + }$
C
$C{N^ - }$, $O_2^ + $
D
$CO,$ $O_2^ + $
Solution
(a) $C{N^ – } = 14$ electrons ; $CO =14$ electrons
$B.O. =$ $\frac{1}{2}[10 – 4] = \frac{6}{2} = 3$.
