The number of unpaired electrons in a parmamagnetic diatomic molecule of an element with atomic number ` 16` is :

A

2

B

3

C

4

D

1

Text Solution

Verified by Experts

The correct Answer is:
A
Suppose the diatomic molecule is X.
Then , molecular orbital electronic configurations of
`._16X=sigma1s^2,overset***sigma1s^2,sigma2s^2,overset***sigma2s^2,sigma2p_z^2,pi2p_x^2~~pi2p_y^2, overset***pi2p_x^1~~overset***pi2p_y^1`
Due to presence of two unpaired electrons, it shows paramagnetic character.
