Question

IUPAC Name of the formed compound:

• A. 2,4,6-Tribromo-1-nitrobenzene
• B. 4-Bromonitrobenzene
• C. 1,3,5-Tribromo-2-nitrobenzene
• D. 1,3,5-Tribromo-fluorobenzene

Answer 1

The Correct Option is C

textbf{Step 1: Identify the reagents and reaction mechanism.}
The first step involves diazotization of the aniline derivative, where the amino group is replaced by a diazonium group. In the second step, the diazonium salt undergoes a Sandmeyer reaction, which substitutes the diazonium group with a bromine atom (as indicated by the reaction with NaNO2 and Cu). Step 2: Name the product.
Following the reactions, we have a benzene ring with three bromine atoms at positions 1, 3, and 5, and a nitro group at position 2, giving the IUPAC name: 1,3,5-Tribromo-2-nitrobenzene. \[ \boxed{1,3,5\text{-Tribromo-2-nitrobenzene}} \]
