There are trans fats everywhere in the foods we eat everyday. If something we eat doesn’t have a trans fat then it probably has a saturated fat. Baked goods‚ cookies‚ cakes‚ and frozen foods have high levels of trans fats. Things that are incorporated into almost everyone’s diets.

Bromination of trans- Stilbene to form 1‚2- Dibromo- 1‚2-diphenylethane Abstract 1‚2-dibromo-1‚2-diphenylethane was produced by the bromination of trans-stilbene through the addition of hydrobromic acid (HBr) and hydrogen peroxide (H2O2). This experiment was a greener bromination of stilbene because bromine was generated in situ and ethanol was used as the solvent. The melting point (243.30°C)‚ mass (.427g)‚ and percent yield (45.54) of the crystals were recorded. The FTIR

Name: Leigh O’Neill Date: 10th February 2015 Lab Partner: Sinead Murphy Title: Resolution of Trans-Cyclohexane-1‚2-diamine Abstract: The experiment of resolution of Trans-Cyclohexane-1‚2-diamine was completed using recrystallization. This produced a percentage yield of 85% from a theoretical yield of 2.638g. Introduction: Enantiomers are identical and equal in their physical properties except for optical rotation which can be viewed by polarimetry. Diastereomers have different densities‚ melting
