Tertiary alcohols are a class of organic compounds characterized by a hydroxyl group (-OH) attached to a tertiary carbon atom. A tertiary carbon atom is one that is bonded to three other carbon atoms. This structural feature distinguishes tertiary alcohols from primary and secondary alcohols, where the hydroxyl group is attached to a primary or secondary carbon, respectively.

The general formula for a tertiary alcohol is R3C-OH, where R represents an alkyl or aryl group. Due to the steric hindrance around the tertiary carbon, tertiary alcohols exhibit different reactivity compared to primary and secondary alcohols. For example, they are more resistant to oxidation under mild conditions. However, they readily undergo dehydration reactions in the presence of an acid catalyst to form alkenes.

Tertiary alcohols are also known for their unique properties. For instance, tert-butyl alcohol (2-methyl-2-propanol) is a solid at room temperature, unlike most other simple alcohols which are liquids. This is due to its symmetrical structure and stronger intermolecular forces.

In terms of synthesis, tertiary alcohols can be prepared through the reaction of Grignard reagents with ketones or esters. For example, the reaction of a Grignard reagent with a ketone yields a tertiary alcohol after hydrolysis. Tertiary alcohols find applications in various fields, including as solvents, intermediates in organic synthesis, and in the production of fragrances and pharmaceuticals.
