Making carboxylic acids by oxidising primary alcohols or aldehydes. Chemistry of the reactions. Primary alcohols and aldehydes are normally oxidised to carboxylic acids using potassium dichromate(VI) solution in the presence of dilute sulphuric acid. During the reaction, the potassium dichromate(VI) solution turns from
Replacing the OH group in the COOH of a carboxylic acid by chlorine to make acyl chlorides (acid chlorides)
Simple reactions of carboxylic acids as acids - their reactions with metals and various bases.
The decarboxylation of the salts of carboxylic acids (and some acids) by heating with soda lime.
ESTERIFICATION. This page looks at esterification - mainly the reaction between alcohols and carboxylic acids to make esters. It also looks briefly at making esters from the reactions between acyl chlorides (acid chlorides) and alcohols, and between acid anhydrides and alcohols. What are esters? Esters are derived from
Explains why organic acids are acidic and what affects their relative strengths. Hydrogen ions are always attached to something during chemical reactions. The organic acids are weak in the sense that this ionisation is Differences in acid strengths between carboxylic acids, phenols and alcohols. The factors to consider.
The reduction of a carboxylic acid. The reaction happens in two stages - first to form an aldehyde and then a primary alcohol. Because lithium tetrahydridoaluminate reacts rapidly with aldehydes, it is impossible to stop at the halfway stage. Equations for these reactions are usually written in a simplified form for UK A level
This statement is about the reactions of carboxylic acids to produce salts, esters and acyl chlorides. Before you go on, you should find and read the statement in your copy of the syllabus. Statement 19.1(b)(i): Producing salts. You will find most of what you need on the page carboxylic acids as acids. Some comments:.
Carboxylic Acids Menu. An introduction to carboxylic acids and their salts, including their bonding and their physical properties. Their preparation by the oxidation of primary alcohols and aldehydes, and by the hydrolysis of nitriles.
