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.

Though it has the similar number of carbons like benzene, cyclohexane is saturated. So there arenât any double bonds between carbons like in benzene. It is a colorless liquid with a mild, sweet odor. This can be produced by the reaction between benzene and hydrogen.t is like cyclohexane, but there is one double bond between two carbon atoms in the ring, which makes it unsaturated. Cyclohexene is a colorless liquid, and it has a sharp smell. Cyclohexene is not very stable.
