1. The diene and the dienophile react in a 1:1 ratio in this experiment. However, in the procedure, you add one of the reagents in excess. Which one is in excess and why is this necessary? 2. The product of your experiment is an anhydride, which is easily hydrolyzed by water. Draw the structure of the hydrolyzed product. 3. Predict the NMR of the intended product of your Diels-Alder reaction. 4. State the differences you would see in both the IR and the NMR of the anhydride product compared to the hydrolyzed product.

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
