Estiers

Jun 19, 2020 · According to the International Union of Pure and Applied Chemistry (IUPAC), alcohols are named by changing the ending of the parent alkane name to - ol. Alcohols can be considered derivatives of water (H 2 O; also written as HOH). Like the H–O–H bond in water, the R–O–H bond is bent, and alcohol molecules are polar.
