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. Cyclohexanone is slightly soluble in water and miscible with common organic solvents.he 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.
For instance, a chain consisting of one carbon (a methyl group, CH 3) with an OH group attached to the carbon is called methyl alcohol while a chain of two carbons (an ethyl group, CH 2 CH 3) with an OH group connected to the CH 2 is called ethyl alcohol. For more complex alcohols, the IUPAC nomenclature must be used.
