C<sub>2</sub>F<sub>6</sub>, an odorless halocarbon that meets all requirements of a greenhouse gas: unreactive to OH… and ozone, does not photodissociate from either UV or visible light, is insoluble in water, and absorbs in the infrared spectrum.

C<sub>2</sub>H<sub>3</sub>Cl, synonyms: Ethylene, chloro-; Chloroethene; Chloroethylene; Monochloroethylene; Vinyl chloride; Vinyl chloride monomer. This colorless gas is used mainly to produce polyvinylchloride. As there are no natural sources known for this compound, all sources are anthropogenic. The compound reacts with hydroxyl radicals in the troposphere to yield chlorine radicals.

C<sub>2</sub>H<sub>4</sub>O, a fairly simple aldehyde (second in the analogous series after formaldehyde) that is found in the atmosphere as a result of emissions from the manufacture of acetic acid, plastics, raw materials, and as a product in some polluted air oxidation reactions, for instance, acetaldehyde is found in urban air all over the world.

C<sub>2</sub>H<sub>4</sub>O<sub>2</sub>, a carbonyl compound that is emitted into the troposphere by both natural and anthropogenic processes. In the troposphere, acetic acid is present in the gas phase and is highly water soluble. Since acetic acid is highly water soluble, it is found in high concentration as acidic precipitation, such as in fog water and cloud droplets in urban areas.

C<sub>2</sub>HCl<sub>3</sub>, this is an industrial solvent used primarily for vapor degreasing and cold cleaning. It is an extraction solvent for greases, oils, fats, waxes, and tars, and is used by the textile processing industry to sour cotton, wool, and other fabrics. Exposure to moderate amounts of trichloroethylene may cause various health effects such as headaches, vertigo, visual disturbance, tremors, and dizziness. Death may occur from inhalation of large amounts. People located near or downwind of sites where TCE may be in operation might be exposed to higher levels. It is a carcinogen.

C<sub>3</sub>H<sub>6</sub>O, a carbonyl compound that is found in the atmosphere as a reactive gas. Acetone is considered to be a volatile organic compound (VOC), which is emitted into the atmosphere by industrial processes. Acetone has been linked to the formation of ozone in the troposphere due to the fact that it is a source of free radicals.

C<sub>3</sub>H<sub>6</sub>O, a colorless liquid that enters the atmosphere by emissions from the manufacture of plastics, synthesis of rubber, and as a disinfectant and a preservative.

C<sub>4</sub>H<sub>8</sub>O A highly flammable, corrosive compound that causes burns; the aldehyde of butane. Also a colorless liquid, with a pungent smell that condenses and oxidizes in higher temperature of the atmosphere and contributes to photochemical smog.

C<sub>5</sub>H<sub>10</sub>O is a flammable, volatile, colorless liquid. When this compound evaporates from industrial settings or, more commonly, is produced by tropospheric reactions in urban settings, it can contribute to the creation of ozone.

C<sub>5</sub>H<sub>5</sub>, a colorless volatile liquid which is insoluble in water, soluble in alcohol, and very reactive because of its low vapor pressure and double bonds. From an atmospheric chemistry point of view, isoprene is emitted from trees and plants, globally on the order of teragrams (500 x 10<sup>12</sup> g) per year. This reactive, natural hydrocarbon may influence the oxidative/reductive balance in the biosphere where its concentrations are significant, in regions such as rainforests and large temporal forests. Most isoprene is directly emitted into the atmosphere from plant surfaces and some no doubt condenses on particulate matter. Emission rates from trees are positively correlated with leaf temperature and therefore, to a degree, time of day. Ultimately the carbon in isoprene is oxidized to carbon monoxide and finally carbon dioxide.
