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.

Alcohols are biomolecules that contain at least one hydroxyl group (RâOH). The simplest of all oxygen-containing functional groups, hydroxyl groups add polarity to organic molecules because of the strong electronegative nature of oxygen atoms.arboxyls. Although it may be confusing, carbonyl and carboxyl functional groups (RâCOOH) have similar names for a reason. A carboxyl group contains both a carbonyl group and a hydroxyl group, bonded to the same carbon atom. The name carboxyl derives from combining these two terms, carbonyl + hydroxyl = carboxyl.
