Alcohols, Carboxylic Acids And Esters

Question 1

What are huge properties of methanol, ethanol and propanol?

Answer 1

Dissolve in water to from a neutral solution
React with sodium to produce hydrogen
Burn in air
Are used as a fuel and solvent, and ethanol is the main Alcoa in alcoholic drinks

Question 2

What can be done to ethanol?

Answer 2

It can be oxidises to ethanoic acid, either by chemical oxidising agents or by microbial action. Ethanoic acid is the main acid in vinegar

Question 3

What is ethanoic acid a member of?

Answer 3

The carboxylic acids, which have the functional group -COOH

Question 4

Hat are the properties of carboxylic acids?

Answer 4

Dissolve in water to produce acidic solution
React with carbonates to produce carbon dioxide
React with alcohols in the presence of an acid catalyst to produce ester
Do not ionise completely when dissolved in water or weak acids
Aqueous solutions of weak acids have a higher pH value than aqueous solution of strong acid with the same concentration

Question 5

How is ethyl ethanoate produced?

Answer 5

ethyl ethanoate is the ester produced from ethanol and ethanoic acid

Question 6

What is the functional group of esters?

Answer 6

-COO-

Question 7

What type of compound are esters?

Answer 7

They are volatile compounds with distinctive smells and are used as flavouring and perfumes

Question 8

What do alcohols contain?

Answer 8

The functional group -OH. Methanol, ethanol and propanol are the first three members of a homologous series of alcohols
