Hydrocarbon An organic compound that contains only carbon and

A combustion reaction occurs when a hydrocarbon, which is an organic compound that contains only hydrogen and carbon, reacts with oxygen to produce water and carbon dioxide. In some ways, combustion reactions are the easiest of the types of chemical reactions to identify, because oxygen is always a reactant and the products are always carbon dioxide and water. The general form for a combustion reaction is shown here hydrocarbon + oxygen carbon dioxide + water... 

The name of even the most complex organic com-poimd is based on the name of a hydrocarbon, an organic compound that contains only the elements hydrogen and carbon. Hydrocarbons occur naturally in fossil fuels such as natural gas and petroleum and are used mainly as fuels and the raw materials for making other organic compounds. 

Hydrocarbon An organic compound that only contains carbon (C) and hydrogen (H). 

A student is assigned to identify an unknown compound in an organic chemistry class. She is sure that the compound contains only carbon and hydrogen atoms. In addition, the unknown compound is a saturated hydrocarbon. If there are fourteen hydrogens in a molecule of this unknown compound, and it does not have a ring structure, what is the most likely number of carbons in this compound ... 

Section 2.9 Organic chemistry is the study of compounds that contain carbon. The simplest class of organic molecules are the hydrocarbons, which contain only carbon and hydrogen. Hydrocarbons in which each carbon atom is attached to four otiier atoms are called alkanes. Alkanes have names that end in -am, such as methane and ethane. Other organic compounds are formed when an H atom of a hydrocarbon is replaced with a functional group. An alcohol, for example, is a compound in which an H atom of a hydrocarbon is replaced by an OH functional group. Alcohols have names tiiat end in -ol, such as methanol and ethanol. Otiier oiganic molecules have multiple bonds between a carbon atom and oflier atoms. 

Alkanes are hydrocarbons that contain only single covalent bonds and can be represented by the formula C H2 i2. Alkanes possess a three-dimensional geometry in which each carbon is surrounded by four bonds directed to the comers of a tetrahedron. Methane, the simplest alkane, is an important fuel (natural gas) and a chemical feedstock for the preparation of other organic compounds. The number of stmctural isomers possible for an alkane increases dramatically with the nnmber of carbon atoms present in the molecule. The straight-chain isomer is called a normal alkane others are called branched isomers. 

The simplest organic compounds are the hydrocarbons that contain only the elements of carbon and hydrogen. All the carbon-to-carbon bonds in a hydrocarbon known as an alkane are single C—C bonds. Some common hydrocarbons include methane (CH4), propane (CsHg), and butane (C4Hio)-... 

Chlorinated hydrocarbons (1) Chemical substances containing only chlorine, carbon, and hydrogen. These include a class of persistent, broad-spectrum insecticides that linger in the environment and accumulate in the food chain. Among them are DDT, aldrin, dieldrin, heptachlor, chlordane, lindane, endrin, Mirex, hexachloride, and toxaphene. Other examples include TCE, which is used as an industrial solvent. (2) Any chlorinated organic compounds, including chlorinated solvents such as dichloromethane, trichloromethylene, and chloroform...
