● Organic chemistry is the chemistry of carbon and its compounds.
● Hydrocarbons are organic compounds of just carbon and hydrogen atoms.
● Alkanes are hydrocarbons in which there are only single bonds.
● Alkanes are named in a very systematic way. Review the rules for naming alkanes.
● Isomers are compounds that have the same molecular formulas but different structural
formulas. Review the writing of the various structural isomers of alkanes. Make sure
that each carbon atom has four bonds.
● A functional group is a group of atoms that is the reactive part of the molecule. Review
the general functional groups.
● Macromolecules are large molecules that may have molecular masses in the millions.
Macromolecules are generally composed of repeating units called monomers.
