What is the structure of 3-methyl-3-butanol?

There is no such thing. It would be named 2-methyl-2-butanol (see link below).

"Butan" is a continuous chain of 4 carbons. Starting from one side, the 3rd carbon will have both a methyl group (-CH3) as well as a hydroxyl group (-OH), hence "butanOL". Since the rules of naming require that the lowest numbers be used, and the methyl and hydroxyl groups are on the second carbon, the correct name is in fact: 2-methyl-2-butanol.
