Document Summary
Note: must count in the same direction for all location molecules on a single molecule. Functional group bonds should be at the lowest number possible. When a bond is between two numbers, choose the lowest number. Same molecular formula and structural formula but different arrangement of atoms. 3 requirements (i) alkene (ii) same atom/group of atoms on both c (symmetrical) (iii) two different types of atoms on each side of c. Cis: same atom on the same side of the c=c bond. Trans: same atom on opposite sides of the c=c bond. Can pack more closely together than cis molecules. Saturated hydrocarbons: no double bonds (maxxed out available places to put in hydrogens. Unsaturated hydrocarbons: has double or can include triple bonds (double bonds are more common) Special type of unsaturated hydrocarbon that contains benzene or benzene- like molecules (a ring with alternating single and double bonds) If you have 1 side group, group is 1-(name)
