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 a glass test tube‚ the primary alcohol and secondary alcohols were expected to halogenate‚ however

This reaction is also called‚ methylation. Methylation designates the addition of a methyl group on an atom 7. It is a form of alkylation with a methyl group‚ instead of a larger carbon chain it replaces the hydrogen atom with a methyl group which then yields codeine. Codeine can be used to treat mild to moderate pain‚ primarily used to treat coughing. Codeine is often times combined with other non-narcotic

MONTREAL PROTOCOL: The Montreal Protocol on Substances That Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) is an international treaty designed to protect theozone layer by phasing out the production of numerous substances believed to be responsible forozone depletion. The treaty was opened for signature on September 16‚ 1987‚ and entered into force on January 1‚ 1989‚ followed by a first meeting in Helsinki‚ May 1989. Since then‚ it has undergone

Cyra Vose Klebsiella Pneumoniae #34 MCB 2010C Friday 9:00am Introduction: On November 16‚ 2012 at 0900 I was given case #34. Mr. Joe Blough presented with a sudden high fever (103 degrees Fahrenheit or higher) and mentioned he felt dizzy and had the chills. During this visit Mr. Blough seemed to be coughing and producing sputum. This sputum was thick and had some blood present. I had my assistant collect a sample of the sputum so we could run some tests and hopefully correctly diagnose Mr. Blough

CH4. The other hydrocarbons belonging to this class can be taken as descendents of methane‚ resulted from the substitution of one or more atoms of hydrogen with hydrocarbon radicals. Therefore‚ if one hydrogen atom from methane is replaced by a methyl radical‚ -CH3‚ the hydrocarbon (superior to methane) will have the composition C2H6‚ named ethane. The alkanes can be: with a continuous chain‚ if all the carbon atoms are bound with at most two other carbon atoms‚ and with a branched chain‚ if one
