medium
Which of the following is paramagnetic
A
${N_2}$
B
${C_2}$
C
$N_2^ + $
D
$O_2^{2 - }$
Solution
(c) ${N_2}:KK\sigma{(2s)^2}\sigma*{(2s)^2}\pi {(2{p_x})^2}\pi {(2{p_y})^2}\sigma {(2{p_z})^2}$ (diamagnetic)
${C_2}:KK\sigma{(2s)^2}\sigma*{(2s)^2}\pi {(2{p_x})^2}\pi {(2{p_y})^2}$ (diamagnetic)
$N_2^ + :KK\sigma{(2s)^2}\sigma*{(2s)^2}\pi {(2{p_x})^2}\pi {(2{p_y})^2}\sigma {(2{p_z})^2}$ (paramagnetic)
$O_2^{2 – }:KK\sigma{(2s)^2}\sigma*{(2s)^2}\sigma^* {(2{p_z})^2}\pi {(2{p_x})^2}\pi {(2{p_y})^2}$
$\pi *{(2{p_x})^2}\pi *{(2{p_y})^2}$ (diamagnetic)
