Explore its structure
Choose a part to light it up.
A nitrogen carrying one or two hydrogens. Its spare pair of electrons can pick up a hydrogen ion, so an amine is a base.
From: standard chemistry.
An O-H on a carbon that is not part of an aromatic ring, the group that makes a molecule an alcohol. It both gives and accepts hydrogen bonds, which helps the molecule mix with water.
From: standard chemistry.
An oxygen bridging two carbons, written C-O-C. It accepts hydrogen bonds but has no hydrogen to give, and it is slow to react.
From: standard chemistry.
