Carboxylic Acids Flashcards

All 5 cards in this deck

What are the molecular formulae of methanoic, ethanoic, propanoic and butanoic acids?

$\mathrm{HCOOH}$, $\mathrm{CH_3COOH}$, $\mathrm{CH_3CH_2COOH}$, $\mathrm{CH_3CH_2CH_2COOH}$

What is the formula of the functional group in carboxylic acids?

–COOH (the carboxyl group).

What are the products when a carboxylic acid solution reacts with a metal carbonate?
e.g. ethanoic acid + sodium carbonate

A salt + water + carbon dioxide.
Ethanoic acid + sodium carbonate → sodium ethanoate + water + carbon dioxide

What is the word equation for the oxidation of ethanol?

ethanol + oxygen → ethanoic acid + water

True or false? When propanol is oxidised, propanoic acid is produced.

True. Each alcohol is oxidised to the carboxylic acid with the same number of carbon atoms (plus water).
