Question

$Cl{O}_2$ is paramagnetic due to ______ unpaired electron(s).

Answer 1

Paramagnetic is due to the presence of at least one unpaired electron in the molecule.

$Cl{O}_2$ is paramagnetic as it has an odd number of electrons. $Cl$ has 17 and $O_2$ have 16 electrons. Total is 33 which is odd So 32 electrons are fill in the orbitals and 1 electron is unpaired which is more unpaired electrons in orbitals then that will show paramagnetic.

So, due to 1 unpaired electron $Cl{O}_2$ is paramagnetic
