Electrophilic addition to alkenes takes the following general form: nuc: = nucleophile E+ = electrophile. Electrophilic addition to alkenes starts with the pi electrons attacking an electrophile, forming a carbocation on the most stable carbon.A nucleophile then attacks the carbocation to form the product. There are many different kinds of such addition, including:lectrophilic addition to alkenes takes the following general form: nuc: = nucleophile E+ = electrophile.
