Why are Alkanes Called Saturated Hydrocarbons

Question

Why are alkanes called saturated hydrocarbons?
A) because alkanes are used as solvents for most organic compounds
B) because alkanes are highly reactive organic compounds
C) because alkanes contain only carbon-carbon single bonds
D) because alkanes are found in animal fats and plant oils

Accepted Answer

Alkanes are called saturated hydrocarbons because they contain only carbon-carbon single bonds. This means that the maximum number of hydrogen atoms possible are attached to each carbon atom in the molecule, making it "saturated" with hydrogen atoms. If any more atoms were added to the molecule, they would have to form double or triple bonds with the carbon atoms, making it an unsaturated hydrocarbon.
