Vedclass · Answer

(C) Paramagnetic property depends upon the number of unpaired electrons. Higher the number of unpaired electrons,higher the paramagnetic property will be.$Cu^{2+} = [Ar] 3d^9$,number of unpaired electrons $= 1$$V^{2+} = [Ar] 3d^3$,number of unpaired electrons $= 3$$Cr^{2+} = [Ar] 3d^4$,number of unpaired electrons $= 4$$Mn^{2+} = [Ar] 3d^5$,number of unpaired electrons $= 5$Hence,the correct order of increasing paramagnetic property is $Cu^{2+} < V^{2+} < Cr^{2+} < Mn^{2+}$.

Which one of the following sets correctly represents the increase in the paramagnetic property of the ions?
