MCQ
Which of the following is paramagnetic
- A${N_2}$
- B${C_2}$
- ✓$N_2^ + $
- D$O_2^{2 - }$
${C_2}:KK\sigma{(2s)^2}\sigma*{(2s)^2}\pi {(2{p_x})^2}\pi {(2{p_y})^2}$ (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)
