Allylic Carbons -Carbons that are next to carbons that are doubly bonded. CHAPTER 4 Electrophile Reactions -Electrophile – positive species that is attached. -Nucleophile (Nu) – negative or neutral species that does the attacking. -Slow step – formation of carboncation. -Fast step – nucleophile attacking carbocation. -Faster step – rearrangement. -Markovnikov – H adds to least substituted carbon (least number of carbons directly attached) -Anti-Markovnikov – H adds to most substituted carbon (most number of carbons directly attached).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
