B) propane and butane
C) pentane and hexane
D) nonane and decane
E) none of the above

Alkanes

Saturated hydrocarbons consisting solely of hydrogen and carbon atoms, with single bonds between the carbon atoms, exemplified by molecules such as methane, ethane, and propane.

Freons

A trademarked name for a group of chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) gases used primarily as refrigerants and aerosol propellants, now commonly linked to ozone depletion.

Propellants

Chemicals that are used to propel an object by generating gas under pressure; common in rockets and aerosol cans.
