Methane is a chemical compound with the chemical formula CH4. It is the simplest alkane‚ and the principal component of natural gas. Methane’s bond angles are 109.5 degrees. Burning methane in the presence of oxygen produces carbon dioxide and water. The relative abundance of methane makes it an attractive fuel. However‚ because it is a gas at normal temperature and pressure‚ methane is difficult to transport from its source. It is generally transported in bulk by pipeline in its natural gas form

poisoning leads to the impairment of intracellular and intercellular communication pathways. Its effect on signal transduction leads to build up of free radicals that mediate cell death or injury. Mercury poisoning results from methylmercury. It has inhibitory effects that resemble those of lead and uniquely induces the release of free radicals in cells. Cadmium mainly poisons the cell by displacing essential nutrients such as calcium‚ zinc‚ iron and copper from biomolecules. The displaced metals

nomenclature you should review them now. Alcohols are usually named by the first procedure and are designated by an ol suffix‚ as in ethanol‚ CH3CH2OH (note that a locator number is not needed on a two-carbon chain). On longer chains the location of the hydroxyl group determines chain numbering. For example: (CH3)2C=CHCH(OH)CH3 is 4-methyl-3-penten-2-ol. Other examples of IUPAC nomenclature are shown below‚ together with the common names often used for some of the simpler compounds. For the mono-functional

Comparison of Three Isomers of Butanol SCH 4UI Abstract The Hydroxyl group on alcohols relates to their reactivity. This concept was explored by answering the question “Does each alcohol undergo halogenation and controlled oxidation?” . Using three isomers of butanol; the primary 1-butanol‚ the secondary 2-butanol and the tertiary 2-methyl-2-propanol‚ also referred to as T-butanol‚ two experiments were performed to test the capabilities of the alcohols. When mixed with hydrochloric acid in

The IR spectrum indicates a medium‚ broad peak from 3000-3500 cm-1 representing a hydroxyl group. The hydroxyl group is confirmed from the chromic acid test and the peak in the 13C NMR spectrum with a chemical shift of 80 ppm. These results support the hypothesis. Steric approach control states that steric hindrance will control the stereoselectivity
