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

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

combination of substances. The combination of substances often causes reactions‚ and one of the main groups of reactions is the single-replacement reaction. In Amrita University’s explanation of single replacement reactions‚ a single replacement reaction is defined as a “chemical reaction in which a more reactive element displaces a less reactive element from its compound.” The general formula for single displacement reaction is: AB + C A + BC. This formula shows element A being replaced in its
