Which type of hydrocarbon contains only single carbon to carbon bonds?

Saturated hydrocarbons are characterized by the presence of only single carbon-to-carbon (C-C) bonds. This structural feature means that each carbon atom in the molecule forms four single bonds with other atoms, typically with hydrogen atoms, ensuring that all available bonding sites for carbon are filled. As a result, saturated hydrocarbons do not contain any double or triple bonds, which distinguishes them from unsaturated hydrocarbons, which do have at least one double or triple bond between carbon atoms.

Furthermore, this type of hydrocarbon includes alkanes, which are the simplest form of saturated hydrocarbons, such as ethane and propane. In contrast, unsaturated, cyclic, and aromatic hydrocarbons may have different bonding structures, involving double or triple bonds or cyclic arrangements, making them fall outside the category of saturated hydrocarbons.
