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.

Thus the methyl group is methane minus one hydrogen, with the unspecified valency (hyphen or line) added. To name a group or substituent, simply delete the family suffix of an alkane (-ane) and replace it with the family name for a substituent or group (-yl).-H Bonds. The Simple Alkanes: The simplest alkane is methane, which contains one carbon atom. Its molecular formula is CH4. It has four equivalent C-H bonds, formed by the overlap of the four carbon sp3 hybrid orbitals with the 1s AO of four different hydrogen atoms.
