Question

Quizplus · Accepted Answer

The compound has a tertiary carbon (three alkyl groups attached to it), which is indicated by the prefix "tert" in common nomenclature or "2-methyl" in IUPAC nomenclature. The longest continuous carbon chain is three carbons (prop-), with an OH group attached (prop-1-ol). The methyl group is attached to the second carbon (2-methylprop-1-ol), which can also be named 2-methyl-1-propanol or 2-methylpropan-1-ol. However, the most preferred IUPAC name is 2-methylpropan-2-ol or 2-methyl-2-propanol, which is based on the lowest possible number for the OH group and the methyl group on a branched carbon chain.
