Which of the following is an example of a hydrocarbon? A. chlorofluorocarbons B. acetic acid C. carbon dioxide D. methane

The correct answer is D. methane.

A hydrocarbon is an organic compound that consists only of hydrogen and carbon atoms. Methane is the simplest hydrocarbon, with the chemical formula CH4. It is a colorless, odorless gas that is the main component of natural gas. Methane is also produced by the decomposition of organic matter, such as plants and animals.

Chlorofluorocarbons (CFCs) are a group of chemicals that were once widely used in refrigerants, aerosol propellants, and solvents. CFCs are not hydrocarbons because they contain chlorine atoms.

Acetic acid is a carboxylic acid with the chemical formula CH3COOH. It
