Question

Among 4 VO ,MnO and 2 Cr O , the spin-only magnetic moment value of the species with least oxidising ability is……………….BM (Nearest integer). (Given atomic member V = 23, Mn = 25, Cr = 24)

Answer: .

💡 Solution & Explanation

For 3d transition series; Oxidising power : V+5 < Cr+6 < Mn+7 V+5 : [Ar] 4s0 3d0 Number of unpaired electron = 0 
