functional group will impact the molecular structure of the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). If the OH is bonded to only one other carbon‚ it is a primary alcohol (eg. 1-butanol); if bonded to two other carbons‚ it is a secondary alcohol (eg. 2-butanol); if bonded to three other carbons‚ it is a tertiary alcohol (eg. 2-methyl-2-propanol). Due to the placement of the hydroxyl functional group in each of the degrees of alcohol‚ the reactivity of each should

environmental problems. Waste plastic disposal and excessive use of fossil fuels have caused environment concerns in the world. Both plastics and petroleum derived fuels are hydrocarbons that contain the elements of carbon and hydrogen. The difference between them is that plastic molecules have longer carbon chains than those in LPG‚ petrol‚ and diesel fuels. Therefore‚ it is possible to convert waste plastic into fuels. The non-catalytic pyrolysis process is the nearest technique to commercialization considering

we produced only one of the enantiomer products depending on which enantiomer of Tartaric Acid was used. A reduction is a reaction which generally means adding more carbon-hydrogen bonds to a compound. In a reduction reaction the oxidation number of a carbon atom decreases. The opposite is an oxidation reaction in which the carbon atom oxidation number increases. In compounds with double or triple bonds a reduction reaction can occur by adding hydrogen atoms across the pi-bond. This can change an

Vidallon‚ Mark Louis P. Date Performed: February 20‚ 2012 CHEM44.1 2L Date Submitted: March 12‚ 2012 MIXED-ALDOL CONDENSATION Synthesis of Cinnamaldehyde I. Introduction Cinnamaldehyde‚ cinnamic aldehyde or 3-phenyl-2-propenal is the major constituent of cinnamon oil‚ extracted from several species of Cinnamomum (C. verum‚ C. burmanii‚ C. cassia)‚ under the family Lauraceae‚ a group of evergreen trees. Cinnamon bark (particularly C. verum) yields 0.4-0.8% oil‚ which contains 60-80% cinnamaldehyde

Conversion of Alcohols to Alkyl Halides Title: Conversion of Alcohols to Alkyl Halides Abstract: In this experiment the conversion of alcohols to alkyl halides are investigated through reflux and simple distillation. These are common procedures used to separate substances. After the reflux and distillation is complete 13C NMR and IR spectrum is used to identify the product or products for each reaction: 1a‚ 1b‚ and 2. Every individual in the group was assigned either 1a (1-propanol) or 1b (2-pentanol)

character of having Carbon and Hydrogen atoms only. They are divided into three main categories base on the type of orbital hybridization they have. The three main groups of Hydrocarbons are Alkanes‚ Alkenes‚ and Alkynes (1). Alkanes are sp3-hybridized hydrocarbons characterized by single bonds between carbon atoms included in their chains. Alkanes are also called saturated hydrocarbons because they contain the highest possible H atoms that they can since their single bonds give the Carbon atoms the opportunity

density. PEM fuel cells also promise to become an alternative to batteries in portable electronics‚ such as laptop computers‚ cellular phones‚ and other hand-held devices. The catalysts currently used in PEM fuel cells are Pt nanoparticles supported on carbon black. Pt as a precious metal is expensive‚ and there have been tremendous efforts made to reduce its usage. One way is to make Pt nanoparticles as small as possible to maximize the catalyst dispersion and thus its utilization. Smaller nano particles
