2-methyl-2-butene

I tired visualising it, but I had to jot it down.
It is 2-MethylBut-2-ene.
The longest chain is the 4 cabons, either in the straight line or the and the branch. The functional group is the double bond, which indicates it's an Alkene.
You start naming from the side which has the functional group, which in this case doesn't matter since the double bond is in the middle. So the double bond is 2 carbons from the left (or right).
Finally the methyl group on the branch is on the second carbon as well.
Hope this helps your future naming.!

2-methylbut-2-ene, because if you count from the other end, you get a higher number for the methyl group and the aim is to keep the numbers low.

I would call it 2-methyl-2-butene.
The root chain must be numbered from the end nearest a double bond carbon atom. If the double bond is in the center of the chain, the nearest substituent rule is used to determine the end where numbering starts.
The methyl group establishes the end to start, so it's on No 2 carbon.
IUPAC nomenclature would be 2-butene for the base.

it is 2-methyl 2 -butene or 2-methyl but-2-ene. According to IUPAC nomenclature we should always number the carbon atom in such a fashion which gives minimum number to the double bond carbon. so the numbering for this compound would start from the right most carbon atom and gives us the name as 2 methyl bute-2-ene

In addition to 2-methyl-2-butene, which others have explained very well, the compound is also called isoprene.
