Aldehydes are organic compounds which have the functional group -CHO at the end of a carbon chain. Naming Aldehydes: 1.Count the number of carbon atoms.

CARBOXYLIC ACIDS Since the carboxyl group is polar, carboxylic acids contain dipole-dipole forces, London forces and are able to hydrogen bond. Therefore.

Carboxylic Acids. The functional group of carboxylic acids is the carboxyl group - general form: R - COOH O O C R H O carbonyl group hydroxyl group.

CARBOXYLIC ACID AND ESTERS L.O.: Identify carboxylic acid and esters. Name carboxylic acid and esters.

-COOH or –CO2H

NAMING CARBOXYLIC ACIDS • Select the longest chain of C atoms containing the COOH group; • Remove the e and add oic acid after the basic name • Side chain positions are based on the C in COOH being 1.

Name this carboxylic acids: Methanoic acid Ethanoic acid Butanoic acid 2-Bromobutanoic acid 3-methylbutanoic acid

Carboxylic acids up to C4 are completely soluble in water. They form hydrogen bonds with each other in the solid state. Therefore, they have higher melting points the alkanes of similar Mr Add/draw figure 1. draw dimer of carboxylic acids

ESTERS Or RCOOR’ What is the difference between an acid and an ester?

How to name esters Methyl ethanoate

Name the following esters
