Question

Write the IUPAC name of the given compound:

Hint:

In halogen-substituted benzene compounds, the positions of the substituents are numbered to give the lowest possible numbers to the substituents.

Answer 1

The given compound is a halogen-substituted benzene. The IUPAC name is 3 – Bromo– 1 – chlorocyclohexene.
- The first step is to number the positions of the substituents on the benzene ring. We begin by numbering the ring to give the lowest possible numbers to the substituents.
- Chlorine (Cl) is at position 1, and bromine (Br) is at position 3. The substituents are located at the 1 and 3 positions on the benzene ring.

Step 1: Number the positions of the substituents on the benzene ring starting from the substituent that provides the lowest numbering.


Step 2: Name the compound according to the position of the substituents.
