Explore its structure
Choose a part to light it up.
A carbon carrying both a C=O and an O-H, written COOH. In water it gives up that hydrogen, which is what makes the molecule an acid.
From: standard chemistry.
A C=O joined through an oxygen to another carbon, the link an acid and an alcohol make when they combine. Water can split it back into the two.
From: standard chemistry.
A three-membered ring of two carbons and one oxygen. The ring is strained, so it opens more readily than an ordinary ether.
From: standard chemistry.
