    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

    of CO2 is a result of increased temperatures acceleration of the rate of fermentation. Abstract: We have tested the affects of increased temperature above room temperature on the rate of fermentation of yeast. We had 6 flasks filled with 6mL DI water‚ 2mL Yeast suspension and 6mL glucose of which 3 were at 25°C and 3 were at 37°C. The flasks at 37°C had each mixture pre-heated at 37°C for 2 minutes before being combined and then added to the flask where it was put into the bath heated to 37°C.

    The objective of the deicer lab was to successfully conduct experiments to determine the usefulness of magnesium chloride as a deicer. To find how successful magnesium chloride is as a deicer‚ experiments were conducted to determine the freezing point depression‚ enthalpy of dissolution‚ the impact on the surrounding environment‚ and also the expenses of using magnesium chloride as a deicer. For magnesium chloride to be determined as a good deicer‚ the reaction with water needs to be exothermic so
