Question

Use the reaction below to answer the three questions that follow: SNa DMSO 16. What effect would changing the nucleophile to ethoxide have on the rate of the reaction above? a. The rate would increase. C. The rate would decrease. b. There would be no reaction. d. No effect on rate would be observed. 17. What effect would changing the iodine atom to a chlorine atom have on the rate of the reaction? a. There would be no reaction. c. The rate would increase. b. The rate would decrease. d. No effect on rate would be observed. 18. By what reaction mechanism will the above reaction proceed? a. Sl b. Sy2 c. d. free radical reaction chain reaction 19. A student is attempting to synthesize the product shown below through an Sy2 reaction. They came up with five possible synthesis schemes. Which reaction is most likely to give the desired product? Br OOCH3 CH3OH d. - Br OOCHз , CH3BT CH3BT

Answer 1

16) The ethonide I weaker nucleophile ion ( than ona) is a a sua Tc. The rate would decrease 17) 'Ci is a weaker Leaving group than 'I' So, Tb. The pate would decrease ! 18) The mechanism is: b. SNP 13 The most likely process is CHIBP as, it is SN2, the alkyl halide being smaller reacts faster.
