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

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

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)

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

APPLICATIONS OF ORGANIC COMPOUNDS IN LASER TECHNOLOGY WHAT IS AN ORGANIC COMPOUND? An organic compound is any member of a large class of gaseous‚ liquid‚ or solid chemical compounds whose molecules contain carbon. Organic chemistry is the science concerned with all aspects of organic compounds. Organic synthesis is the methodology of their preparation.

One type of which is the mostcommon and the simplest type that is only composed of hydrogen and carbon atom‚ the hydrocarbons.All hydrocarbons are insoluble in water due to their relatively non-polarity. Instead‚ they mix withrelatively non-polar solvents like dichlromethane or carbon tetrachloride. Hydrocarbons can be characterize on the way in which carbon atoms are connected‚ the aliphaticand aromatic hydrocarbons. Aliphatic hydrocarbons‚ from the Greek word aleiphar (fat

Hydrocarbons are compounds that contain only carbon and hydrogen atoms. Hydrocarbons may be divided into two large classes namely: Saturated hydrocarbons and unsaturated hydrocarbons. Saturated hydrocarbons are the simplest type of organic compounds. They are hydrocarbons in which all carbon- carbon bonds are single bonds. An example of a saturated hydrocarbon is an alkane. Unsaturated hydrocarbons are hydrocarbons that contain one or more carbon-carbon multiple bonds like double bonds‚ triple bonds
