Among the species given below, the total number of diamagnetic species is ___. H a t o m , N O 2 m o n o m e r , 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

Correct answer

0

Step-by-step solution

H - atom = paramagnetic N O 2 = odd unpaired electron species paramagnetic O 2 - (superocide) = One unpaired electrons in π * M.O. paramagnetic S 2 (in vapour phase) = same as O 2 , two unpaired e - s are present in π * M.O. paramagnetic
