Organic Chemistry II Lab Diels Alder Reaction Purpose: In this experiment a Diels-Alder reaction was used to form the products. Cyclopentadiene and maleic anhydride were reacted together to form cis-Norbornene-5‚6-endo-dicarboxylic anhydride. 7-oxabicyclo{2.2.1}hept-5-ene-2‚3-dicarboxylic anhydride was also produced through a Diels-Alder reaction with the combination of furan and maleic anhydride.

Dances with Wolves Reaction Paper Reaction or response papers are usually requested by teachers so that you’ll consider carefully what you think or feel about something you’ve read. The following guidelines are intended to be used for reacting to a reading although they could easily be used for reactions to films too. Read whatever you’ve been asked to respond to‚ and while reading‚ think about the following questions. * How do you feel about what you are reading? * What do you agree or

Oscillating chemical reaction Aim: The overall reaction rate and concentrations of some reaction intermediates of certain chemical reactions oscillate‚ even in a homogeneous system. This phenomenon is commonly found in living organisms. These periodical variations occur when a feedback mechanism is available in which a product changes the reaction rate. In this experiment will produce oscillations in both time and space in the concentrations of cerium(IV) and cerium(III) in the BZ reaction. Use the magnetic

Grignard Reaction: Synthesis of Triphenylmethanol Hai Liu TA: Ara Austin Mondays: 11:30-2:20 Abstract: In this experiment‚ phenylmagnesium bromide‚ a Grignard reagent was synthesized from bromobenzene and magnesium strips in a diethyl ether solvent. The Grignard reagent was then converted to triphenylmethanol‚ a tertiary alcohol with HCl. The reaction for phenylmagnesium bromide was: The reaction for Grignard to triphenylmethanol was: In the formation of the Grignard reagent

compare that relative reactivity of Na and k -Sodium and potassium react somewhat similar when reacting with water however they are slightly different. Sodium moves because of the hydrogen coming off of it and has a low melting point while potassium’s reaction is faster and enough heat is produced to set light to the hydrogen coming off of it. Each leaves a pink color hue in the water. Discuss the similarities and differences in the behavior of the metals tested with water relative to their positions
