Anthracene -9-methanol and 3 equivalents of N-methylmaleimide were mixed with water in an Erlenmeyer flask and heated to reflux( Diels-Adler reaction) TLC was prepared using a 1:1 ratio ethyl acetate: hexane. We got Rf=0.8 for N-methylmaleimide Rf=0.6 for anthracene and Rf=0.3 for the mixture. What information does this provide?

Experiment 7: Grignard Reaction. Introduction Discovered by French chemist Victor Grignard, the reaction that now bears his name is an example of the preparation of an organometallic reagent. In this lab, phenylmagnesium bromide is the Grignard of interest, and it will be added to an aldehyde to produce an alcohol. Lab Objectives 1. To study organometallic reagents in general. benzophenone. 2. To prepare phenylmagnesium...
