Carboxylic Acids Flashcards

All 6 cards in this deck

What is the functional group of the carboxylic acids?: $-COOH$
Name the first four members of the homologous series of carboxylic acids.: Methanoic acid, ethanoic acid, propanoic acid, butanoic acid
What is formed when a carboxylic acid reacts with a carbonate?: A salt, water and carbon dioxide (seen as fizzing).
What happens when a carboxylic acid dissolves in water?: It ionises to form an acidic solution (pH less than 7).
What is formed when a carboxylic acid reacts with an alcohol, and what is needed?: An ester, using an acid catalyst.

e.g. ethanoic acid + ethanol $\rightarrow$ ethyl ethanoate
True or false? Both alcohols and carboxylic acids form acidic solutions when added to water.: False. Carboxylic acid solutions are acidic, but alcohols dissolve to give neutral solutions.
