Flashcards in c3.5 Organic Chemistry Deck (10):
What type of organic compound is ethyl propanoate
Organic compounds such as ethyl propanoate are used in perfumes.
Give two properties of these compounds that make them suitable for use in perfumes. 
Pleasant smell 
Volatile (evaporate easily) 
Ethanol is an alcohol.
One use of ethanol is in alcoholic drinks.
Give two other uses of ethanol. 
What type of reaction produces ethanoic acid from ethanol?
Solutions of ethanoic acid and hydrochloric acid with the same concentration have different pH values.
Explain why the solution of ethanoic acid has a higher pH than the solution of hydrochloric acid. 
ethanoic acid is a weak acid
because it partially ionises
Name the ester made from ethanol and ethanoic acid. 
What type of chemical is used as a catalyst in this reaction? 
Esters are used in perfumes because they smell pleasant and are volatile.
What does volatile mean? 
evaporates easily / quickly
When acids react with scale a gas is produced.
What is the name of the gas?
