Chemistry · Aldehyde and Ketones: Nature of carbonyl group, nucleophilic addition to >C=O group, relative reactivities of aldehydes and ketones
Acetic acid is obtained when:
Acetic acid is obtained when:
- A. methyl alcohol is oxidised with potassium permanganate
- B. calcium acetate is distilled in the presence of calcium formate
- C. acetaldehyde is oxidised with potassium dichromate and sulphuric acid
- D. glycerol is heated with sulphuric acid
Step-by-step solution
Acetaldehyde (CH3CHO) undergoes oxidation with potassium dichromate in acidic medium to yield acetic acid (CH3COOH). This is a standard laboratory and industrial method for preparing carboxylic acids from aldehydes.
