Vedclass · Answer

(B) In the qualitative analysis of nitrate,a brown ring is formed due to the formation of $[Fe(H_2O)_5(NO)]^{2+}$. The chemical reaction is: $FeSO_4 + NO + 5H_2O 	o [Fe(H_2O)_5(NO)]SO_4$.In this complex,the central metal ion is $Fe^{2+}$. The ligands are five $H_2O$ molecules and one $NO$ molecule.The coordination number is the total number of sigma bonds formed by the ligand atoms with the central metal ion,which is $5 + 1 = 6$.Both the Assertion and the Reason are correct,but the Reason does not explain why the complex is brown-coloured (which is due to charge transfer). Therefore,the Reason is not the correct explanation of the Assertion.

Assertion : When $NO$ reacts with $FeSO_4$,a brown coloured complex is formed.
Reason : In the complex,the coordination number of $Fe$ is $6$.
