Question 5 (27 pts.) Synthesize the target) molecules on the right from the starting molecules the left. this can not be done in one reaction. Give reagents and conditions and the intermediate molecules at each step. Do not show any mechanisms or transient intermediates. If other isomers are formed at any step then you need to indicate this but you do not need to draw their structures. NOZ CO2H SO3H

Q 10 - Synthesis question. Show how the starting material can be converted to the product through any of the reactions you have learned in Ochem-l and Ochem-Il. Show all the reagents you need and indicate the stereochemistry when appropriate. You do not need to show arrow pushing like in a mechanism question, only the reactions. If a chiral molecule is formed mark the chiral center with an asterisk (*) and write "racemic" below the structure. All carbon atoms in...

You are told synthesize cumene starting from benzene and any other reagents. You find 1- chloropropane in the lab and decide to attempt a Fridel Crafts alkylation. Upon completion of the experiment, a H-NMR reveals two products: a minor product with six signals and a major product with 5 signals. Provide the mechanism for the formation of both products. 2. Provide the reaction for chlorination of benzene using electrophilic aromatic substitution, it's complete mechanism including formation of "super" electrophile, and...

Please explain the mechanisms!
1. Propose a synthesis for each of the following problems starting with reagent shown and using any other organic or inorganic reagents allowed in each problem. Multiple steps are required. The number of steps you use does not matter. Reactions should give the desired product as a major product. For full credit show the product of each step (reaction). If you make use of organometallic reagents such as Grignard, Wittig, organolithium, organosodium, organocopper, etc. you must...
