(Discuss) Proposed since September 2016 . </Td> </Tr> <P> In organic chemistry, a saturated compound is a chemical compound that has a chain of carbon atoms linked together by single bonds . Alkanes are saturated hydrocarbons . An unsaturated compound is a chemical compound that contains carbon - carbon double bonds or triple bonds, such as those found in alkenes or alkynes, respectively . Saturated and unsaturated compounds need not consist only of a carbon atom chain . They can form straight chain, branched chain, or ring arrangements . They can have functional groups, as well . It is in this sense that fatty acids are classified as saturated or unsaturated . The amount of unsaturation of a fatty acid can be determined by finding its iodine number . </P> <P> Unsaturated compounds are those in which addition reaction can be obtained . </P>

When do we say that a solution is unsaturated
