Carboxylic acids Flashcards
What is the functional group of carboxylic acids?
-COOH
What are the first 4 carboxylic acids
Methanoic acid, ethanoic acid, propanoic acid, and butanoic acid
What can carboxylic acids react to form?
Salts
What do the salts formed end in?
-anoate e.g. methanoic acid will form methanoate, ethanoic acid, and ethanoate
Ethanoic acid + sodium carbonate –>
sodium ethanoate + water + carbon dioxide
What will reacting a carboxylic acid in an aqueous solution with metal carbonates produce?
Salt, water, and carbon dioxide
What will reacting aqueous carboxylic acids with metals form?
Salt and hydrogen
Ethanoic acid + magnesium –>
Magnesium ethanoate + hydrogen
How are esters formed?
Carboxylic acids react with alcohols in the presence of an acid catalyst to form them.
How can ethanoic acid also be made?
By oxidizing ethanol
What causes the ethanol to ferment?
Microbes, like yeast
How can ethanol also be oxidized?
Using oxidizing agents
Ethanol + oxygen –>
Ethanoic acid + water
How is vinegar made?
Ethanoic acid is dissolved in water
