`O_2` molecule is

Options

A. ferrimagnetic
B. ferromagnetic
C. paramagnetic
D. diamagnetic

Answer

C

Explanation

`O_(2), sigma 1s^(2),sigma^(**),1s^(2),sigma 2s^(2) sigma^(**) 2s^(2), sigma 2p_(z)^(2), pi2p_(xx)^(2), pi2p_(y)^(2), pi^(**)2p_(x)^(1), pi^(**) 2p_(y)^(-1)` Since `O_2`, molecule has two unpaired electrons, therefore, it is paramagnetic.
