Which of the following functional groups characterizes primary aliphatic amines?

💡 Solution & Explanation

Primary aliphatic amines are structurally characterized by the presence of the amino functional group attached to an alkyl chain, represented by the chemical formula minus NH-two. Hydroxyl groups define alcohols, whereas carbonyl groups with hydrogen define aldehydes. Amines act as organic bases due to the lone pair of electrons residing on the nitrogen atom.
