National 5 Chemistry Alcohols and Carboxylic Acids

Front

Uses of Alcohols

Back

Alcohols are used as fuels due to their high flammability and clean burning. They are also used as solvents.

Front

Describe the solubility of Alcohols

Back

Methanol, ethanol, and propanol are miscible with water. Solubility decreases as the size of the alcohol increases.

Front

How do the Melting and Boiling Points of Alcohols change with increasing size? Why?

Back

As alcohols increase in size, their melting and boiling points increase due to stronger intermolecular forces.

Front

What is the Functional Group of Alcohols?

Back

An alcohol contains a hydroxyl functional group, represented as ─OH.

Front

General Formula for Saturated Alcohols

Back

Saturated, straight-chain alcohols can be represented by the formula CnH2n+1OH.

Front

Uses of Carboxylic Acids

Back

Carboxylic acids are used in preservatives, soaps, medicines, and household cleaning products like vinegar.

Front

Solubility of Carboxylic Acids

Back

Methanoic, ethanoic, propanoic, and butanoic acids are miscible in water. Solubility decreases as size increases.

Front

How do the Melting and Boiling Points of Carboxylic Acids change with increasing molecular size?

Back

As carboxylic acids increase in size, their melting and boiling points increase due to stronger intermolecular forces.

Front

Functional Group of Carboxylic Acids

Back

Carboxylic acids contain a carboxyl functional group, represented as ─COOH.

Front

General Formula for Saturated Carboxylic Acids

Back

Saturated, straight-chain carboxylic acids can be represented by the formula CnH2n+1COOH.
