4.6 Carboxylic Acids

4.6.1C Know that carboxylic acids contain the functional group -COOH

The functional group of carboxylic acid is -COOH

4.6.2C Understand how to draw structural and displayed formulae for unbranched-chain carboxylic acids with up to four carbon atoms in the molecule, and name each compound

4.6.3C Describe the reactions of aqueous solutions of carboxylic acids with metals and metal carbonates

REACTION OF CARBOXYLIC ACIDS

Carboxylic acids dissolve in water to produce acidic solutions
So it can react as an acid

carboxylic acid + metal → salt + hydrogen

carboxylic acid + metal carbonate → salt + H2O + CO2 (bubbles are formed)

4.6.4C Know that vinegar is an aqueous solution containing ethanoic acid

VINEGAR

Aqueous solution containing ethanoic acid
