Question 1

State the uses of alcohols

Answer 1

Fuels - alcohols are very flammable and they burn with a clean flame
Solvents - substances which may not be soluble in water may be in alcohols

Question 2

Describe the properties of alcohol

Answer 2

Smaller alcohols are soluble in water, after 4 carbons their solubility decreases( this is due to the size of the molecule increases)
As alcohol increases in size their melting and boiling point increases as the strength of the intermolecular force increases

Question 3

Explain fully why butan-1-ol has a higher melting point than propan-1-ok

Answer 3

As alcohols increase in size their melting and boiling point increases as the strength of the intermolecular force increases

Question 4

Name the functional group in an alcohol

Answer 4

Hydroxyl

Question 5

Draw the functional group in an alcohol

Answer 5

• OH

Question 6

Draw propan-2-ol

Question 7

Draw 2-methylbutanol

Question 8

Name alcohols from their diagrams

Question 9

DRaw alcohols upto C8

Question 10

State the uses of carboxylic acids

Answer 10

Carboxylic acids are used in the preparation of preservatives, soaps and medicines

Question 11

Describe the properties of carboxylic acids

Answer 11

Small carboxylic acids (up to 4 carbons) are miscible (soluble) in water, any bigger are insoluble.
As the size of carboxylic acid increases the melting and boiling point increases, this is due to the increasing strength in intermolecular forces

Question 12

State the functional group in carboxylic acids

Answer 12

Carboxyl

Question 13

Draw the functional group in carboxylic acids

Answer 13

• COOH

Question 14

Name and draw carboxylic acids up to C8
