Alcohols Flashcards

All 7 cards in this deck

What is the functional group of the alcohols?: $-OH$
Name the first four members of the homologous series of alcohols.: Methanol, ethanol, propanol, butanol
What happens when one of the first four alcohols reacts with sodium?: The sodium reacts and hydrogen gas is given off (fizzing).
What is produced when an alcohol reacts with an oxidising agent?: A carboxylic acid.

e.g. ethanol is oxidised to ethanoic acid.
What are the main uses of methanol, ethanol, propanol and butanol?: As fuels and as solvents; ethanol is also the alcohol in alcoholic drinks.
What conditions are used to produce ethanol by the fermentation of sugar solution with yeast?: Yeast added to sugar solution, kept warm (about 25–45 °C) and anaerobic (no oxygen/air).
True or false? When one of the first four alcohols burns completely in air, the products are carbon dioxide and water.: True. Alcohols are flammable and burn in air, releasing energy, e.g. $C_2H_5OH + 3O_2 \rightarrow 2CO_2 + 3H_2O$ .
