An oil spill can be defined as an accidental or deliberate dumping of oil or petroleum products into the ocean and its coastal waters‚ bays‚ and harbors‚ or onto land‚ or into rivers or lakes (Holum 1977). Between one and ten million metric tons (one metric ton is 1000 kilograms) of oil are put into the oceans every year. The oil is released‚ most often‚ in small yet consistent doses from tankers‚ industry‚ or on shore waste disposal (Boesh‚ Hersher‚ et al. 1974). Tanker spills cost the United

1) What is the purpose of ice or cold water? To cool down the gas so that it condenses and turns into a liquid. 2) when the gas collecting tube is upside down‚ give a property of this gas. It is less dense than air. 3) Why is a pencil used in drawing the origin line in chromatography? If pen was used‚ it will dissolve giving colours and so‚ the experiment won’t be accurate. Pencil doesn’t interfere with the results. 4) When using ethanol‚ give a better apparatus arrangement‚ and why? Cover

is usually illustrated by alkanes due to their C-C single bond. It is usually represented using the Newman projection. eclipsed staggered anti-staggered gauche-staggered chair boat The second type of stereoisomerism is geometric isomerism which is common in alkenes. Geometric isomers differ in physical properties such as melting points and boiling points. ex. cis (same side) trans (opposite side) For alkenes where cis-trans configuration

greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic byproducts and recycles acetone in the epoxidation reaction. Introduction The epoxidation of an alkene creates an epoxide that is reactive to nucleophiles. This is important in organic chemistry as well as biological sciences. For example epoxide hydrolase aids in purification during drug metabolism. The mechanisms for Oxone and mCPBA epoxidation can

into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene) and alkynes (e.g. ethyne) have carbon-carbon double or triple bonds‚ and are said to be unsaturated. Aromatic hydrocarbons are cyclic compounds whose structure is related to that of benzene‚ with six-electrons in a six-membered ring. For this experiment‚ hexane will be used as an example of saturated hydrocarbons (alkanes)‚ cyclohexene will be
