Vedclass · Answer

(D) Paramagnetic substances are those that contain one or more unpaired electrons.$Cu^{+2}$ has electronic configuration $[Ar] 3d^9$,which contains $1$ unpaired electron.$Fe^{+3}$ has electronic configuration $[Ar] 3d^5$,which contains $5$ unpaired electrons.$Cr^{+3}$ has electronic configuration $[Ar] 3d^3$,which contains $3$ unpaired electrons.$MnO$ contains $Mn^{+2}$ ion,which has electronic configuration $[Ar] 3d^5$. However,in the solid state,$MnO$ is an antiferromagnetic substance because the magnetic moments of the $Mn^{+2}$ ions are aligned in a way that they cancel each other out.

Which of the following substances is not paramagnetic?
