The pairs of species of oxygen and their magnetic behaviour are noted below. Which of the following presents the correct description ?A. `O_(2)^(+) , O_(2)` -Both paramagneticB. `O,O_(2)^(2-)`-Both paramagneticC. `O_(2)^(-),O_(2)^(2-)`, Both diamagneticD. `O^(+),O_(2)^(2-)`-Both paramagnetic

Answer» Correct Answer - A
MOT configuration of `O_(2)` and `O_(2)^(+)`
`O_(2),(sigma1s^(2))(sigma^(**) 1s)^(2)(sigma2s)^(2)(sigma^(**)2s)^(2)(sigma2p_(z))^(2)(pi 2p_(x)^(2)=pi 2p_(y)^(2))(pi^(**) 2p_(x)^(1)=pi^(**)2p_(y)^(1))`
Number of unpaired electron=2 so paramagnetic. `O_(2)^(+): (sigma 1s)^(2)(sigma^(**)1s^(2))^(@)(sigma2s)^(2)(sigma^(**)2s)^(2)(sigma2p_(z))^(2)`
`(pi2p_(x)^(2)=pi2p_(y)^(2))(pi^(**)2p_(x)^(1)=pi^(**)2p_(y)^(0))`
Number of unpaired electrons =2 , so paramagnetic .
