The carbonyl group, a carbon-oxygen double bond, is the key structure in these classes of organic molecules: Aldehydes contain at least one . . Fatty Acids. It ionizes, discharging the H from the hydroxyl aggregate as a free proton (H+), with the rest of the O conveying a -ve charge. where R refers to the rest of the molecule that the carboxyl group is attached to. (If it were hydrogen atom, the compound would be a carboxylic acid.) They occur widely in nature and are also synthetically manufactured by humans. Hydroxyl groups are simply an oxygen bonded to a . In general, carboxylic acids are represented by the formula RCOOH, where R is a hydrocarbon group. Attach a chlorine (Cl) atom to the parent chain at the beta carbon atom, the second one from the carboxyl group: Cl-C-C-COOH. This is the reason that the carboxylic acid group must always be on the end of a carbon chain. A carboxylic acid group is a functional group with the formula R-COOH, where R is an organic residue. Carboxyl groups have the formula -C (=O)OH, usually written as -COOH or CO 2 H. Carboxylic acids are a class of molecules which are characterized by the presence of one carboxyl group. The ester, which is organic compound derived from a carboxylic acid and an alcohol in which the OH of the acid is replaced by an OR group, looks somewhat like an ether and also somewhat like a carboxylic acid.Even so, compounds in this group react neither like carboxylic acids nor like ethers; they make up .
