A) What kind of isomers are methylenemalonic acid and maleic acid: constitutional or geometric and would methylenemalonic acid yield a geometric isomer under the conditions of this experiment (isomerized dimethyl maleate to dimethyl fumarate by placing dimethyl maleate into a test tube into boiling water with light shining on it and traces of bromine and then placing it into an ice water bath to crystallize it). If yes give the structureof the product, if not explain why not.
B) Estimate the percentage of your dimethyl maleate (0.5764 g or mL) that was converted to dimethyl fumurate (0.83 g was obtained) and would it be possible to prepare dimethyl maleate in good yield from dimethyl fumurate(using bromine and light) under experimental conditions that permitted recovery of the dimethyl maleate? Why or why not?
