Abstract The bromination of trans-cinnamic acid was completed to determine dibromide’s stereochemical structure and its mechanism. After the addition of bromine to trans-cinnamic acid‚ the product was identified by its melting point and infrared spectrum resulting in erythro-2‚3-Dibromo-3-phenylpropanoic acid after comparing similar properties. Introduction In this lab‚ the bromination of trans-cinnamic acid was completed to determine dibromide’s stereochemical structure‚ and from there determine

Experiment 2: Fractional Distillation of a Mixture of Two Unknowns Background: Boiling is a process familiar to anyone who has cooked pasta or brewed tea. As heat is applied to a pan of water‚ the temperature of the water increases until it reaches 100°C (212°F). At this temperature‚ additional heat causes the water to bubble vigorously as the liquid water is converted into gaseous water‚ or steam. Most organic liquids will behave in a similar fashion. On heating‚ the temperature of the liquid

Olah‚ the Hungarian-born U.S. chemist whose research is focused on hydrocarbons‚ strongly advocates the introduction of methanol as a chemical energy carrier. The basic idea is that‚ to be sure‚ we need to find a replacement for the short chain alkanes that constitute the major part of gasoline‚ aviation spirit‚ etc.‚ and which are used as the source of motive power for vehicles. Currently‚ attention seems to be focused on two rival alternatives. The first is ethanol‚ produced by time-honoured
