A cycloalkane is a cyclic hydrocarbon, meaning it has a ring structure composed entirely of carbon atoms with hydrogen atoms attached to them. Therefore, it still contains the same number of carbon atoms as the corresponding alkane but each carbon atom in the ring is bonded to two other carbon atoms instead of three, resulting in two fewer hydrogen atoms.
