Question
Consider the species Cl2+, Cl2, and Cl2–. Which of these species will be paramagnetic?Only Cl2Cl2+ and Cl2Cl2 and Cl2–Cl2+ and Cl2–all three are paramagnetic
Solution
The paramagnetic species are those which have unpaired electrons.
-
Cl2: The Cl2 molecule has all paired electrons, so it is diamagnetic.
-
Cl2+: In Cl2+ ion, one electron is removed, so it has one unpaired electron. Therefore, it is paramagnetic.
-
Cl2-: In Cl2- ion, one electron is added, so it has an unpaired electron. Therefore, it is paramagnetic.
So, the species that will be paramagnetic are Cl2+ and Cl2–.
