1. Why do you think alkenes would rather undergo catalytic hydrogenation by syn addition rather than anti addition? Support your answer with an example. (4 pts) 2. What does the word stereoselectivity mean and how does it apply to the catalytic hydrogenation of alkenes? (2 pts) 3. What is the correlation between the heat of hydrogenation of an alkene and its degree of substitution? (2 pts)

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....

S. Show how you would prepare the following compound using an organometallic reagent. You may use any hydrocarbons, organohalides, alcohols and/or carbonyl compounds that have five of fewer carbon atoms You may also use any needed reagents and solvents OH This one as well. He quits grading when you get two mistakes. 6. Propose a synthesis of the following compound using a Wittig reaction. You may use triphenylphosphine (Ph P) and any reagents containing five carbons or less as starting...

9. Chlorine, bromine and iodine all react with alkenes such as ethene in an addition reaction. (a) Write the equation for the bromination of ethene, and name the product. (b) Explain why this is called an addition reaction. (c) Describe what you would see if you bubbled ethene through a solution of bromine in an organic solvent such as hexane. 10. If you use a permanganate test to distinguish between cyclohexane and cyclohexene, in which would the purple color of...

Grignard Reaction 1. Draw your complete reaction, including the formation of the Grignard reagent and the reaction with your carbonyl compound. Below each reagent, write its molecular weight and density (if a liquid). Also write how much of each material you will use in ml (if liquid), grams, and moles. Also include the molecular weight and melting point of your final product. 2. How many moles of Grignard reagent are you synthesizing? What mass of water could fully react with...
