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...

Chem 210: Chapter 8 Correct 100% Addition - ANSWERA reaction involving an increase in the number of groups attached to the alkene and a decrease in the number Regiochemistry - ANSWERThe orientation of a chemical reaction on an unsymmetrical substrate. In additions to alkenes, the regiochemistry of the addition involves which part of the reagent adds to which end of an unsymmetrical alkene. Regioselective reaction - ANSWERA reaction in which one direction of bond making or bond breakin...
