Final answer:
Alkanes with only single carbon-carbon bonds are known as saturated hydrocarbons.
Step-by-step explanation:
Saturated hydrocarbons with only single carbon-carbon (C-C) bonds are called alkanes or saturated hydrocarbons. Alkanes have the general formula CnH2n+2.
They are the simplest hydrocarbon species and are composed entirely of single bonds and saturated with hydrogen. Alkenes and alkynes are unsaturated hydrocarbons that contain double or triple bonds between carbon atoms, whereas alkanes contain only single bonds.
