What is the IUPAC name of tertiarybutyl alcohol?

Question

Accepted Answer

1. Recognize tert-butyl alcohol: its structural formula is $ (CH_3)_3C	ext{-}OH $.

2. Determine the longest carbon chain containing the OH group: choose a 3-carbon chain (propane) that includes the central (bearing OH) carbon, so the parent is propane.

3. Number the chain to give the OH the lowest possible locant: the OH is on the central carbon, so it is at carbon $2$ (propan-2-ol).

4. Identify substituents: the remaining methyl group attached to the central carbon gives a methyl substituent at carbon $2$, so the full name is $2$-methylpropan-$2$-ol.

5. Compare options: (1) $2$-Methylpropan-$2$-ol matches exactly. The other options propose incorrect chain lengths or substituent positions.
