Essay on Experiment a: Cis-Trans Conversion of Butenedioic Acid

In the lab we filled the first beaker up with water. Then we took a pipet (filled with the liquid) and dropped water droplets onto the

What is the stereochemistry for the bromination of trans-cinnamic acid, and how is it formed?

4. Write a structural diagram equation to represent the reaction between each alcohol and HCl(aq).

1. Fill the graduated cylinder nearly to the top with water, with a tall glass tube open at both ends (the water level with act as the closed end).

24) Separate the formed crystals (benzoin) and allow them to dry, then take the MP.

1. Move the lid of the container up or down. Record the resulting volume and pressure

Hydrogens, alkyls, or aryls bonded to carboxyl groups—made up of a carbonyl group and a hydroxyl group—are known as carboxylic acids. Derivatives of carboxylic acids include acid chlorides, esters, anhydrides, amides, and generally nitriles. These derivatives are formed by the replacement of the hydroxyl group with a different electronegative heteroatom substituent, which can be a single atom, such as a chlorine atom, or a group of atoms, such as in the formation of

Fill a test tube about 1/3 full with cold tap water for use in step 34.

5.Wait 5 minutes. During these 5 minutes, set all 4 of the syringe plungers on the gas measuring mechanism at 2mL.

Repeat steps 4–11 two more times. Be sure to record your observations in the data tables in your lab notebooks, in the rows for trials 2 and 3. (Can you separate the dyes of grape soda using space sand?). The entirety of the Procedures.

XIII. Carefully remove the copper metal from the filter paper onto the watch glass. (with a spatula) Place a 400 ml beaker on a hot plate contained with water. Carefully place the watch glass before the water boils to dry the copper metal. (Use the tongs to handle the hot watch glass)

1) Separate the solid from the liquid in the beaker by decanting the liquid. Ask your instructor to demonstrate the correct procedure.

Dispense .5 mL water into the already weighed conical vial, replace cap and face insert on its down side.

4. Prepare a vacuum filtration apparatus using a buchner funnel. Obtain one filter paper for each one of your samples, weigh them and record their mass in your notebook (label them with a pencil to be able to differentiate them later).

Remove foam plug from the inoculate flask and pour it into a cuvette. Incubate it at 37°C and the optical density readings at 600nm every 10-15 mins. Pour into the
