Organic chemistry. Please explain how you get the answers.
. Tert-butylmethyl ether (MTBE) is a gasoline additive. In theory, it can be prepared by the two reactions shown below. However, in practice, only one of the reactions produces MTBE. Which reaction produces MTBE? What is the major product of the other reaction? Reaction A: potassium tert-butoxide +methyl iodide Reaction B: MTBE tert-butyl bromide + sodium methoxide Provide structures for each of the missing compounds in the following sequence of reactions. Show stereochemistry in your products. TsCl, pyr Nal NaCN DMF SM2 reactions occur with inversion of configuration. Propose a sequence of steps to prepare the nitrile (RCN) from the starting material. Notice there is no inversion. More than one step will be required Br CN Ph Ph Predict the major substitution product of each of the following reactions. Indicate whether the reaction follows an Sw1 or Sw2 pathway Cl Nal CH3OH a. acetone OTs EtOH NaCN DMF
