4.Chemical Bonding and Molecular Structure
medium
In which of the following pairs the two molecules have identical bond order
A
${N_2},O_2^{2 + }$
B
${N_2}$, $O_2^ - $
C
$N_2^ - $, ${O_2}$
D
$O_2^ + $, ${N_2}$
Solution
(a) $B.O.$ $ = \frac{1}{2}[\,{N_b} – {N_a}]$
${N_2} = \frac{1}{2}[10 – 4] = \frac{6}{2} = 3$; $O_2^{2 + } = \frac{1}{2}[10 – 4] = \frac{6}{2} = 3.$
