Question

The products formed in the following reaction sequence are:

• A.
• B.
• C.
• D.

Hint:

In organic reactions, the reduction of nitro compounds by Sn/HCl forms amines, which can then undergo diazotization. This is a key step in forming various organic products, such as aldehydes and alcohols.

Answer 1

The Correct Option is C

The reaction sequence is as follows: \[ NO_2 \xrightarrow{\text{Br}_2, \text{AcOH}} NO_2 \quad (\text{Nitro compound}) \] \[ NO_2 \xrightarrow{\text{Sn, HCl}} NH_2 \quad (\text{Amine formation}) \] \[ NH_2 \xrightarrow{\text{NaNO}_2, \text{HCl}, 273K} \text{Nitrosonium ion} \] \[ \text{Nitrosonium ion reacts with} \text{ethanol to form acetaldehyde.} \] Thus, the products formed are \(\text{CH}_3\)-CHO and \(\text{Br}\) at the end. \bigskip
