2. Above is S-adenosylmethionine (SAM). Note that R'-S-R is a very good leaving group. You do not need to know anything else about sulfur to answer this question. a) SAM is famous for being a biological methylating agent. Draw a classical organic methylation reaction between [CH3-CH2-CH2-O]¯ and CH3Br using the arrow formalism, clearly indicating the product. b) Among all of the elements in the above reaction, which has the greatest electronegativity? c) Write a rate law for this reaction: d[P]/dt = d) In the above rate law, what are the units of k? e) Examining the structure of SAM, you notice that three different carbon atoms are bound to sulfur. Circle these carbon atoms and label them (starting from the 12 o'clock position and going clockwise) #1, #2, and #3. Which of these, if any, are chiral carbons?
