Concept:The compound is an alcohol, so the longest carbon chain containing the
−OH group is named as an alkanol.
Explanation:The longest continuous chain contains three carbon atoms, so the parent name is propane.
The
−OH group is attached to carbon 2, giving propan-2-ol.
There is also a methyl group,
CH3, attached to the same carbon 2.
Therefore, the complete IUPAC name is 2-methylpropan-2-ol.
Answer:D. 2-methyl propan-2-ol
