Organic molecules are also named using the functional group approach 2hexanone 2hexanol 2chlorohexane The rule is that functions assume their distinct identity when separated by –CH2– groups Thus, the carbonyl, C=O, and hydroxy, OH, of a carboxylic acid, RCOOH, are part of a single function and are NOT "alcoholplusketone"Chapter 3 Alcohols, Phenols, and Ethers 2 3 Alcohols 4 The Hydroxy (—OH) Functional Group •The hydroxyl group (—OH) is found in the alcohol and phenol functional groups (Note that's not the same as hydroxide, OH, which is ionic) –in alcohols, a hydroxyl group is connected to a carbon atom –in phenols, —OH is connected to a benzene ringC Functional Groups Compound Classification Compound Classification CH 3 —OH alcohol CH 3 —NH 2 amine O CH 3 —C—NH 2 amide carboxylic acid H 2 C CH 2 aldehyde CH 3 —O—CH 3 ether ketone carboxylic acid Q7 Classify each of the following according to its functional group a alkene CH 3 —CH 2 —CH=CH—CH 3
Study Notes The concept of functional groups is a very important one We expect that you will need to refer back to tables at the end of Section 31 quite frequently at first, as it is not really feasible to learn the names and structures of all the functional groupsAmides (RCONH 2) take the suffix "amide", or "carboxamide" if the carbon in the amide group cannot be included in the main chainThe prefix form is both "carbamoyl" and "amido" Amides that have additional substituents on the nitrogen are treated similarly to the case of amines they are ordered alphabetically with the location prefix N HCON(CH 3) 2 is N,NCH 3 CH 2 NHCH 2 CH 3;
