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.

1 The ground state conformation of cyclohexane is a fully staggered conformation which is shaped somewhat like a chair. 2  In this conformation there is no torsional strain at all, and as we shall see later, no strain of any kind.3  Cyclohexane is unique in being the only cyclic hydrocarbon which is completely strain-free. Another conformation which is important in any conformational analysis is the transition state, or maximum energy conformation on the rotational path.For cyclohexane this is the so-called half-chair conformation, in which now 5 carbons are co-planar, and only one is puckered out of the plane.
