Step-by-step explanation:
A saturated hydrocarbon is defined as the hydrocarbon in which there are only single bonds between the combining atoms.
On the other hand, a cyclic hydrocarbon is a ring structure in which hydrogen and carbon atoms are joined together.
Hence, a saturated cyclic hydrocarbon is a ring structure of hydrogen and carbon atoms joined together through single bonds only.
In a saturated cyclic hydrocarbon molecule, each carbon atom is bonded with two hydrogen atoms.
Therefore, we can conclude that the ratio of carbon atoms to hydrogen atoms in a saturated cyclic hydrocarbon is 1:2.
