The number of saturated and unsaturated bonds in cyclohexane are :

Cyclohexane is a saturated cyclic hydrocarbon with the molecular formula C6H12. In its structure, six carbon atoms are arranged in a ring, and each carbon atom is bonded to two hydrogen atoms to satisfy its valency. This results in a total of 18 covalent bonds: 6 carbon-carbon (C-C) single bonds forming the ring and 12 carbon-hydrogen (C-H) single bonds. Saturated compounds are defined as those containing only single bonds between carbon atoms, whereas unsaturated compounds contain double or triple bonds. Since cyclohexane consists entirely of single bonds, it has 18 saturated bonds and 0 unsaturated bonds. Although it has one degree of unsaturation due to the presence of a ring, this does not imply the presence of pi bonds or unsaturated linkages.
