Detailed explanation-1: -Cycloalkanes are alkanes that have a monocyclic ring structure. Since all the carbon-carbon bonds in cycloalkanes are single bonds, they are considered to be saturated hydrocarbons.

Detailed explanation-2: -Alkanes are saturated hydrocarbons. This means that contain only carbon and hydrogen atoms bonded by single bonds only. The general formula for an alkane is CnH2n+2.

Detailed explanation-3: -Alkanes are also called saturated hydrocarbons, whereas hydrocarbons that contain multiple bonds (alkenes, alkynes, and aromatics) are unsaturated.

Detailed explanation-4: -Alkanes are a series of compounds that contain carbon and hydrogen atoms with single covalent bonds. These are known as saturated hydrocarbons. This group of compounds consists of carbon and hydrogen atoms with single covalent bonds.

Detailed explanation-5: -All four valencies of each carbon atom of the alkane molecule are bonded with either hydrogen atoms, carbon atoms or both by single covalent bonds, indicating that each carbon skeleton of an alkane is fully saturated. Hence, alkanes are known as saturated hydrocarbons.
