3 - bromo - 6,7 - dimethyl - 6 - octene
6 - bromo - 2,3 - dimethyloct - 2 - ene
6 - bromo - 2,3 - dimethyloctene
2,3 - dimethyl - 6 - bromooct - 2 - ene

Explanation:

Step1: Identify the parent chain

The parent chain is an octene (8 - carbon chain with a double bond).

Step2: Number the chain

Number the chain to give the double bond the lowest number. The double bond is between carbons 2 and 3.

Step3: Locate substituents

There are two methyl groups (at carbons 2 and 3) and a bromo group (at carbon 6).

Step4: Write the name

According to IUPAC rules, substituents are listed in alphabetical order (bromo before methyl). The name is 6 - bromo - 2,3 - dimethyloct - 2 - ene.

Answer:

6-bromo-2,3-dimethyloct-2-ene
