What is the difference between aliphatic amine and aromatic amine (aniline)?

An aliphatic amine (e.g. methylamine) has a freely available lone pair and is more basic than ammonia; in aniline the lone pair delocalises into the ring, making it a much weaker base.

An aliphatic amine (e.g. methylamine) has a freely available lone pair and is more basic than ammonia; in aniline the lone pair delocalises into the ring, making it a much weaker base. A reliable way to keep them apart is to focus on what each one is defined by, not just the similar-sounding words.
