These exercises are hosted courtesy of Professor Peter Dibble, who has created and compiled them over many years.
04 Addition Reactions to Nonpolar Pi Bonds (Alkenes and Alkynes)
05 Addition Reactions to Conjugated Pi Systems (Dienes, etc.)
06 Addition Reactions to Polar Pi Bonds (Carbonyls, Nitriles, etc.)
The exercise are not listed in numerical order because it makes more sense to group the electrophilic additions together and to group the nucleophilic additions together. Since I cannot edit these documents, I cannot renumber them.
