Which of the following structural statements strictly identifies a tertiary () amine? — Amines Chemistry Question

💡 Solution & Explanation

Amines are classified by the degree of alkylation of the nitrogen atom, not the carbon atom. A tertiary ($3^\circ$) amine is defined as having the nitrogen atom directly bonded to three alkyl or aryl groups (three carbon atoms). A primary amine like tert-butylamine has nitrogen attached to a tertiary carbon, but it is still a primary amine.
