Identify a tertiary alcohol:
Correct answer: B. 2 - Methyl - 2 - butanol
- A. 2-pentanol
- B. 2 - Methyl - 2 - butanol
- C. 2,2-Dimethyl - 1 propanol
- D. 3 - Methyl - 2 -butanol
Explanation
A tertiary alcohol is one where the hydroxyl (-OH) group is attached to a carbon atom that is bonded to three other carbon atoms. In 2-methyl-2-butanol, the -OH group is on carbon 2, which is also bonded to two methyl groups and an ethyl group.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
