Cyclohexanone is the organic compound with the formula (CH 2) 5 CO. The molecule consists of six-carbon cyclic molecule with a ketone functional group. This colorless oil has an odor reminiscent of peardrop sweets as well as acetone.Over time, samples assume a yellow color due to oxidation.

Cyclo pentane (C5H10). Cyclopenta ne is commonly represented by the structural formula. and cyclohexane (C6H12) by the structural formula. Note the pentagon between the five carbon atoms for cyclopentane, and the hexagon between the six carbon atoms for cyclohexane.The single lines between the atoms represent single covalent bonds. Note that each carbon atom has four bonds (valency 4), and each hydrogen atom has one bond (valency 1).ote the pentagon between the five carbon atoms for cyclopentane, and the hexagon between the six carbon atoms for cyclohexane.
