WebAbout. Functional groups are group of atoms or bonds that define the function of the hydrocarbon that they get attached to. Examples: Alcohol, Aldehyde, Ketone, Carboxylic acid, Halogens, Double & Triple covalent bonds. Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. Polymers are macromolecules which are formed by certain repeating units. These repeating units are called monomers. Monomers have some functional groups which react with each other to form a long polymeric chain.
