Which among the following is paramagnetic ?
Cl2O
ClO2
Cl2O7
Cl2O6
B.
ClO2
A species with one or more unpaired electron is paramagnetic.
Number of valence electrons in Cl2O
= 7 x 2 + 6 = 20 (even)
Number of valence electrons in ClO2
= 7 + 6 x 2 = 19 (odd)
Number of valence electrons in Cl2O7
=7 x 2+ 6 x7= 56 (even)
Number of valence electrons in Cl2O6
= 7 x 2 + 6 x 6 = 50 (even)
Thus, ClO2 is paramagnetic due to the odd electron.
Sulphur does not exist as S2 molecule because
it is less electronegative
it is not able to constitute bonds
it has ability to exhibit catenation
of tendency to show variable oxidation states
