Bromination Of Cinnamic Acid. You will use your textbook and your knowledge of organic chemistry to predict the stereochemical outcome of the product. Back in your hood, securely support the separatory funnel over the flask.
Bromination And Elimination
This is important in the determination of dibromide’s stereochemical structure, as a. Take your separatory funnel to the hood, put 8.2 ml of a 1.25 m solution of bromine in acetic acid into the funnel and stopper it immediately. Attach a heating mantle and variac and heat the mixture to a gentle reflux. You will use your textbook and your knowledge of organic chemistry to predict the stereochemical outcome of the product. You will then perform the reaction and use the melting point of the product to test your hypothesis. Deuteriation of bromobenzoic acids in the presence of homogeneous platinum catalyst. Since this attack can occur both at positions 2 and 3, and because the reaction proceeds stereospecifically with inversion, both bromonium ions will give rise to mutually identical pairs of enantiomeric. Obtain 4.0 ml of a 1.0 m solution of bromine in methylene chloride in the addition funnel. Back in your hood, securely support the separatory funnel over the flask. Web the bromination of cinnamic acid leads to two intermediate enantiomeric cyclic bromonium ions which are subsequently attacked by a nucleophilic bromide ion.
Web weigh your cinnamic acid unknown sample into a 50 ml erlenmeyer flask and add 6.0 ml of glacial acetic acid. Back in your hood, securely support the separatory funnel over the flask.
