(a) Describe, giving equation , a chemical reaction which is characteristic of saturated hydrocarbons( or alkanes)
(b) what is an oxidising agent ? Name two oxidising agents which can oxidsise ethanol to ethanoic acid.
(c ) Describe iobe rection of a crboxylic acid.

In which of the following reactions does nitric acid acts as an oxidising agent ?

Give the chemical reaction in which dihydrogen acts as an oxidising agent.

Potassium permanganate is prepared by fusing pyrolusite with caustic potash in the presence of air or some oxidising agent which gives a green mass. The green mass is then extracted with water and treated with a current of Cl_2 to form potassium permanganate. In the laboratory, it is prepared by oxidising a manganese (II) salt by peroxosulphate. It acts as an oxidising agent in neutral, alkaline or acidic solutions. Name two oxidising agents which can be used in place of air for the above reaction.

List in tabular form three physical and two chemical properties on the basis of which ethanol and ethanoic acid can be differentiated.
