$N_2,O_2,S_2,C_2,B_2.$

• A. 3
• B. 4
• C. 1
• D. 2

Answer 1

The correct option is A 3

Correct option-A.

$N_2\to \sigma 1s^2{\sigma }^{\ast }1s^2\sigma 2s^2{\sigma }^{\ast }2s^2\pi 2P{x}^2\pi 2P{y}^2\pi 2P{z}^2$(Diamagnetic)

$O_2\to \sigma 1s^2{\sigma }^{\ast }1s^2\sigma 2s^2{\sigma }^{\ast }2s^2\pi 2P{x}^2\pi 2P{y}^2\pi 2P{z}^2{\pi }^{\ast }2Py{\pi }^{\ast }2Pz$(Paramagnetic)

$S_2\to \sigma 3s^2{\sigma }^{\ast }3s^2\sigma 3P^{2}x\pi 3P{y}^2\pi 3P{z}^2{\pi }^{\ast }3Py{\pi }^{\ast }3Pz$(Paramagnetic)

$C_2\to \sigma 1s^2{\sigma }^{\ast }1s^2\sigma 2s^2{\sigma }^{\ast }{s}^2\pi 2P{y}^2\pi 2P{z}^2$(Diamagnetic)

$B_2\to \sigma 1s^2{\sigma }^{\ast }1s^2\sigma 2s^2\pi 2P{x}^2$(Diamagnetic)
