Explore its structure
Choose a part to light it up.
A C=O with a carbon on each side. Its oxygen accepts hydrogen bonds but has no hydrogen to give, and it resists oxidation better than an aldehyde.
From: standard chemistry.
An O-H fixed directly to a benzene ring. The ring makes that hydrogen easier to give up than an ordinary alcohol's, which is why many phenols act as antioxidants.
From: standard chemistry.
A nitrogen bonded to three carbons, with no hydrogen of its own. Its spare pair of electrons can still pick up a hydrogen ion, so a tertiary amine is a base.
