name the following molecule by its iupac name.
name the following molecule by its iupac name.
Answer
Explanation:
Step1: Identify the parent - chain
The parent - chain is a benzene ring.
Step2: Number the substituents
We start numbering from the carbon with the methyl group ($\text{CH}_3$) as carbon - 1. Then, the chlorine ($\text{Cl}$) is at carbon - 2 and the bromine ($\text{Br}$) is at carbon - 4.
Step3: Write the IUPAC name
The substituents are listed in alphabetical order. So the IUPAC name is 1 - methyl - 2 - chloro - 4 - bromobenzene.
Answer:
1 - methyl - 2 - chloro - 4 - bromobenzene
