Discussion: In the first part of the experiment‚ chronoamperometry was used to determine the diffusion coefficient of ferricyanide. The chronoamperogram can be seen in Graph 1. The chronoamperogram shows three distinct regions. [1A] Region “a” is where the electrode potential is higher than the ferricyanide’s potential‚ so no reduction reaction takes place. Region “b” is where the potential is decreased to a potential much lower than that of ferricyanide. This results in the ferricyanide consuming

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

three carbonyl’s serving as the “legs” of the stool and the mesitylene is the “seat” of the stool and is position on one face of the octahedral. This form of coordination is relatively common with olefins and metal atoms‚ the most famous being ferrocene‚ (cyclopentadiene)2Fe. It is composed of two 5-membered rings situated directly above and below the metal center. It looks like an iron sandwich. The reaction of molybdenum hexacarbonyl and mesitylene is unstable with respect to air. Because
