A functional group is a group of atoms in a structure that determines the characteristic reactions of a compound. In an alcohol, the hydroxyl group is bonded to an alkyl group. This is a chain of methyl groups with the formula CnH2n+1. The hydroxyl and methyl groups are covalently bonded. Bonds are the attraction of atoms or ions that hold a compound together. The bonds in an alcohol are always covalent. These are chemical bonds formed by the sharing of one or more pairs of electrons between two atoms. Covalent bonds are relatively weak bonds.
