Question

Among the species given below, the total number of diamagnetic species is

$H$ atom, $N O_{2}$ monomer, $O_{2}^{-}$ (superoxide), dimeric sulphur in vapour phase,
$M n_{3} O_{4}, (N H_{4})_{2} [F e C l_{4}], (N H_{4})_{2} [N i C l_{4}], K_{2} M n O_{4}, K_{2} C r O_{4}$

Open in App

Solution

Paramagnetic: $H, N O_{2}$ monomer, $O_{2}^{-}$ (superoxide), $S_{2}$ (Vapour), $[M n_{3} O_{4}$ is mixed oxide of $M n^{+ 2}$ and $M n^{+ 3}$ ], $(N H_{4})_{2} [F e C l_{4}]$ , $(N H_{4})_{2} [N i C l_{4}]$ , $K_{2} M n O_{4}$
Diamagnetic: $K_{2} C r O_{4}$
