NCERT Exemplar Class 12 Chemistry solutions Chapter 12 Aldehydes, Ketones and Carboxylic Acids.NCERT solutions for Class 12 Chemistry Chapter 12 Aldehydes, Ketones and Carboxylic Acids.NCERT notes Class 12 Chemistry Chapter 12 Aldehydes, Ketones and Carboxylic Acids.A chemical reaction between ethanoic acid and sodium hydroxide (a base) is shown below: it produces sodium ethanoate and water when ethanoic acid reacts with sodium hydroxide: A salt molecule and a molecule of water are formed when the acid reacts with a base. (An ester) (Sodium hydroxide) (Soap) (Alcohol)Īnalogous to a weak acid, ethanoic acid reacts with bases. As a result of this electron cloud attraction, the more electronegative oxygen atom of the carboxylic acid group forms a hydrogen bond with the lesser electronegative hydrogen atom. In liquid and vapour form, Ethanoic acid is typically found as dimers due to hydrogen bonds that form between two molecules of the acid. There is the possibility that it also has a hydroxyl group (–OH) tying it together with an acetyl group (–CH 3CO). It consists of a carboxylic acid functional group (–COOH) attached to a methyl group (–CH 3). Molar mass (or molecular mass) of the compound is 60,05 g / mol.ĭespite its simple and elementary structure, ethanoic acid is still one of the simplest carboxylic acids after ethanoic acid.
