(4) Carbonyl Compounds - Reactions Of Carboxylic Acids - Aqa A2 Chemistry - Unit 4 - 3.4.5

Front 1

Reactions with:

1) Metals form?

Back 1

A salt and hydrogen gas.

Front 2

Reactions with:

1) Bases forms?

Back 2

Salt & Water.

Front 3

Reactions with:

1) Carbonates forms?

2) This is used as?

Back 3

1) A salt, Carbon Dioxide & Water.

2) It's the tesst we use to see if carboxylic acids are present.

Front 4

Testing for Carboxylic acids:

1) We use?

2) Equation?

3) Observation?

4) A test?

Back 4

1) NaHCO3

2) CH3COOH + NaHCO3 --> CH3COONa + H2O + CO2.

3) CO2 evolved thus effervescence.

4) Put in a lighted splint as it'll go out due to the CO2.

Front 5

Reducing Carboxylic Acids:

1) Agent?

– Reason?

Back 5

1) LiAlH4.

– Because NaBH4 is not a strong enough reducing agent to reduce the carboxylic acid.

Front 6

Esterification:

1) Is?

2) Equation?

3) Done by?

Back 6

1) Reacting an alcohol and a carboxylic acid to form an ester and water.

2) R-COOH + R-OH <--> R-COO-R + H2O.

3) Heated under reflux using a sulphuric acid catalyst.

Front 7

Naming esters:

E.g. Methanol + Ethanoic acid would form?

Back 7

The part only attached to one of the oxygen atoms = the 'alkyl'

The part Attached to both of the Oxygen atoms = the '-oate'

E.g. Methyl Ethanoate.
