- this is a multiple step synthesis. you must provide all necessary reaction conditions (HBr, HgSO4, etc.) and the products produced after each step of the synthesis.Help! Need the reagents and mechanism for the following synthesis. Also, how did it become meta directing? Thanks!Draw the neutral organic starting material. The Hint: The reaction conditions support electrophilic addition of Br2 to an alkene's C=C double bond, which would normally yield a dibromo product. However, the product has only one bromine atom, with a C–O bond on the adjacent carbon. This fragment is diagnostic for a halohydrin, where an oxygen nucleophile (water or alcohol) reacts with a bromonium intermediate to generate the O–CH2CH2–Br motif. Work backwards to determine what the starting material must look like. There should be an alcohol and an alkene in the neutral organic starting material.
