Since, two methyl groups are also present at 5 and 6 positions, so the correct IUPAC name of the compound is 5,6-dimethylhept-2-ene.

Q. The IUPAC name of the following molecule is

5,6-Dimethyl hept-2-ene

2,3-Dimethyl hept-5-ene

5,6-Dimethyl hept-3-ene

5-isopropylhex-2-ene

The longest chain contains $7 C$ -atom, so the root word is hept and suffix -ene is added for double bond along with its position. Since, two methyl groups are also present at $5$ and $6$ positions, so the correct IUPAC name of the compound is $5, 6$ -dimethylhept- $2$ -ene.
