Epinephrine Structural Diagram- page 72 [pic] About: - Epinephrine has several uses‚ including increasing ventilation of lungs through relief of bronchodilation‚ increasing cardiac output‚ increasing systolic blood pressure‚ dilating blood vessels involved in crisis response - Clinically‚ epinephrine plays a lifesaving role in countering the effects of anaphylactic shock. It relaxes smooth muscle‚ though at different receptors. Physical Properties: - high boiling points and melting

Subject: Experiment 23: Stereochemistry of the Addition of Bromine to trans-Cinnamic Acid Introduction/Abstract: The purpose of this experiment was to carry out the bromination of trans-cinnamic acid‚ to determine the stereochemistry of the dibromide product of 2‚3-dibromo-3-phenylpropanoic acid‚ and find out whether the reaction proceeds by the usual bromonium ion mechanism or some other mechanism. In this experiment trans-cinnamic acid was mixed with glacial acetic acid and stirred in which

melting point which should be around 240 ºC along with a flame test which should be green-blue. CHEMICAL PROPERTIES TABLE See Attached Lab Notebook Copies REACTION MECHANISM In this lab we used multiple techniques to complete and verify the bromination of trans-stilbene. First technique we used was to reflux the mixture; this contains having the mixture boiling so it will evaporate while the condenser will recondense the solvent which is boiling off so the solvent may stay in the reaction.

Organic Chemistry II Laboratory (ABCT357) Although studying fundamental theories of chemistry in the class is important to understand the concept of chemistry‚ carrying out experiments to corroborate the theories is also important. It is very important for students to get used to experiments in order to speed up their experiments. Expt.1. Acetylation of α-D-glucopyranose Add slowly 2.5 g (0.014 mol) of powdered D-glucose in small portions (roughly in 7-10 portions and 5 min for each addition)
