However‚ many such as PAHs‚ aromatic amines‚ benzene are not necessarily mutagenic by themselves‚ but through metabolic processes in cells they produce mutagenic compounds. Reactive oxygen species (ROS) - These may be superoxide‚ hydroxyl radicals and hydrogen peroxide‚ and large number of these highly

The second is the sixth topic outline: “Pollution”‚ specifically “Air pollution” and “Water pollution.” In the tape the narrator asserts that PET‚ material used in plastic bottles‚ is a type of benzene which is a carcinogen. In addition to releasing harmful benzene to the locals‚ the plastic bottles are often littered which causes water pollution. This water pollution can cause sickness and destruction of habitat.

| Reactions of Grignard Reagents with Carbonyls | | | Tuesday 1:30 | 2/28/2012 | | Introduction This experiment explores the reactivity pattern for the addition of Grignard reagents to three different carbonyl groups: a ketone‚ an ester‚ and a carbonate. Grignard reagents are organometallic compounds that have a carbon-metal bond‚ such as carbon-magnesium. Grignard reagents are formed from the reaction of an alkyl‚ cycloalkyl‚ or aryl halide and magnesium metal in dry ether

RECRYSTALLIZATION Group Medical Technology Organic Chemistry Laboratory ABSTRACT Recrystallization is one of the simplest and most widely used technique for purifying organic solids through the differences in solubility at different temperatures. It is also the process in which the solid to be crystallized is dissolved to either a hot solvent or a hot solvent mixture and is cooled in a solution.In this experiment‚ acetanilide‚ the crude product of acetylation of aniline and acetic anhydride
