Hex = six.
Other suffixes
Pent = five.
But = four.
Prop = three.

Tetra. This prefix means four.
Methyl. This is called an alkyl. It is derived from methane. So, it has one carbon.
4) 3,3,4,4.
These numbers are the position where methyl groups are bonded.
The longest carbon chain will be six-carbon long.
The molecule has four methyl functional groups. These count as subchains.
