Question

When freshly prepared FeSO 4 ​ is added to the sodium nitrate solution followed by the addition of concentrated H 2 ​ SO 4 ​ dropwise then brown ring complex is formed. Which of the following characteristics is CORRECT for the formed complex

TestHub · Accepted Answer

Explain the question: Identify the correct property of the brown ring complex.

Concept: Brown ring test and nitrosyl complex.

Solution:

The brown ring complex formed is $[F e (H_{2} O)_{5} (NO)] S O_{4}$ .

$NO$ acts as a nitrosyl ligand ( $N O^{+}$ ) and bonds through the nitrogen atom.

Hence, the complex has an $F e - N$ linkage.

The given IUPAC name in the option is incorrect.

The EAN value is not correctly stated as 36 for this complex in the JEE context.
