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.

The spectrum for cyclohexene, (C 6 H 10) also has few strong bands. The main band is a strong CH stretch from the CH 2 groups at about 3000 cm-1. The CH stretch for the alkene CH is, as always, to the left of 3000 cm-1.ook for aldehyde type C-H absorption bands. These are two weak absorptions to the right of the C-H stretch near 2850 cm-1 and 2750 cm-1 and are caused by the C-H bond that is part of the CHO aldehyde functional group.
