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...

BCH 462 Exam 4 Questions With 100% Correct Answers Fatty Acid Synthesis - answerFatty acids are built in several passes, processing one acetate unit at a time. The acetate is coming from activated malonate in the form of malonyl-CoA. Each pass involves reduction of a carbonyl carbon to a methylene carbon. Overall, repeating four-step sequence that elongates the fatty acyl chain by two carbons at each step, uses NADPH as the electron donor. Two enzyme-bound -SH groups serve as activating...
