Organic Chemistry: the chemistry of carbon and also of living  things Carbon compounds Binds other carbons to form vast array of molecules Always makes 4 bonds (valence of 4) Organic molecules have covalent bonds Form polar covalent bonds when a carbon atom bonds with strong electronegative atoms Carbons can form multiple covalent bonds by donating 2 or more electrons Organic molecules have three-dimensional shapes Hydrogen, nitrogen, sulfur, phosphorus and oxygen are prevalent in organic molecules
