What type of bonds do saturated molecules contain?

Saturated molecules are characterized by having only single bonds between carbon atoms. This means that all available bonding sites for carbon in the molecule are occupied by single bonds rather than double or triple bonds. In saturated hydrocarbons, for example, each carbon atom can bond with as many hydrogen atoms as allowed by its tetravalency, resulting in the maximum number of hydrogen atoms for a given carbon skeleton. This contrasts with unsaturated molecules, which contain either double or triple bonds, allowing for fewer hydrogen atoms attached. By definition, the presence of double or triple bonds indicates that the molecule is unsaturated, thus reinforcing that saturated molecules exclusively have single bonds.
