Amines have basic properties because of the presence of
A) a carboxyl group in such compounds
B) a lone pair of electrons on the nitrogen atom
C) a positive charge on the nitrogen atom
D) acidic hydrogen atoms on the nitrogen atom

Question

Quizplus · Accepted Answer

Amines have a lone pair of electrons on the nitrogen atom which can accept a proton and behave as a base, giving them basic properties. However, the presence of a carboxyl group (A) would make the compound acidic, and a positive charge on the nitrogen atom (C) would make the compound basic but not necessarily an amine. Additionally, acidic hydrogen atoms on the nitrogen atom (D) would make the compound acidic rather than basic.
