Meaning
Carboxylic Acids are organic compounds with a Carbon atom which has a double bonds to an Oxygen atom and a single bond to an OH group. The general formula is CnH2nO2.
About Carboxylic Acids
- Carboxylic Acids are a homologous series of organic compounds.
- The functional group of the Carboxylic Acids is the double bond between a Carbon atom and an Oxygen atom and the single bond to an OH group.
- Carboxylic Acids are long chains of Carbon atoms covalently bonded together with the the final Carbon atom in the chain as a COOH group.
Examples

Reactions of Carboxylic Acids
Neutralisation
Carboxylic Acids can be neutralised to produce organic salts.
\(2HCOOH + 2K → 2HCOOK + H_2\)
\(2CH_3COOH + MgO → (CH3COO)_2Mg + H_2O\)
\(C_2H_5COOH + NaOH → C_2H_5COONa + H_2O\)
\(2C_3H_7COOH + MgCO_3 → (C_3H_7COO)_2Mg + H_2O + CO_2\)
Esterification
Carboxylic Acids may react with alcohols to produce compounds known as esters which have the functional group -COO-.
- Methanoic Acid + Ethanol → Ethyl Methanoate + Water
\(HCOOH + C2_H_5OH → HCOOC_2H_5 + H_2O\)
- Ethanoic Acid + Ethanol → Ethyl Ethanoate + Water
\(CH_3COOH + C_2H_5OH → CH_3COOC_2H_5 + H_2O\)
- Propanoic Acid + Propanol → Propyl Propanoate + Water
\(C_3H_5COOH + C_3H_7OH → C_2H_5COOC_3H_7 + H_2O\)
- Butanoic Acid + Propanol → Propyl Butanoate + Water
\(C_3H_5COOH + C_3H_7OH → C_3H_5COOC_3H_7 + H_2O\)
