Explain Lewis base and a nucleophile
Species A is a. Carbon B is an electrophile. Carbon C is a leaving group towards carbon B but also a nucleophile towards carbon D. Carbon D is an electrophile. Oxygen E serves as a leaving group (and also a Lewis acid). When atoms in double or triple bonds serve as leaving groups, one bond remains intact, so that the leaving group doesn't actually "leave," but remains tethered within the similar molecule. This is the case with atoms C and E.
