Question

FeSO4 is a very good absorber for NO, the new compound formed by this process is found to contain number of unpaired electrons :

Answer: C

💡 Solution & Explanation

Fe^2+(aq) + NO + SO4^2-(aq) $\rightarrow$ [Fe(H2O)5(NO)]^2+ + SO4^2-. The complex has $\mu_{eff}$ = 3.89 BM. Hence, no. of unpaired electrons = 3.
