The substituents should be prefixes and come first. You should also specify the number of methyl groups within the name.

So, the correct name would be 2,4-dimethyl-2-pentene.

Alternately, for alkenes, you can specify the location of the double bond with an infix rather than a prefix.

Hence, we could also have said 2,4-dimethylpent-2-ene.

Hope that helps! :)
