Answer:
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 ([tex]CH_3[/tex]). 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.
