CHEM 210 Reactions Test Questions and Answers All Correct Describe the mechanism for the electrophilic addition of a strong acid. - Answer-Step 1) An alkene grabs a hydrogen off of a strong acid, forming a carbocation intermediate. Step 2) The conjugate base of the acid (an anion now) bonds to the open shell carbocation What is the regioselectivity of electrophilic addition reactions? - Answer-Markovnikov What is Markovnikov regioselectivity? - Answer-States that the major product is det...
