a) In the decarboxylative elimination, two different solventsare used, butanone and water. What types of solvents are these andwhy is that important for the ultimate course of reaction in eachcase? b) Starting with (R,R)-2-3-dibromo-3-phenylpropanoic acid,which alkene products you would expect to observe if doing thereaction in water? How about in butanone? Provide reactionmechanisms to support your answers. be different. c) which alkeneproduct would be expected if (S,S)-2,3-dibromo-3-phenylpropanoicacid isomer was used as a substrate? How about (R,S) or (S,R)isomers? explain briefly. d) The final alkene beta-bromostyreneproduct was washed with brine solution. what is the function of thebrine solution?
