Draw structural formula of a tertiary alcohol with the formula C4H8O.

2-methylpropan-2-ol

Explanation:

In this case, we can start with a linear structure of 3 carbons. In carbon 2 we can put a methyl group (). In this same carbon we can put the "OH" group and we will obtain "2-methylpropan-2-ol".

In this molecule, the central atom has 3 bonds with another carbons, so, this central atom is a teritary one. Therefore, we will have a tertiary alcohol.
