Answer 1

Answer:

2.

To oxidise HI & stop backward reaction

Answer 2

In iodination of alkane HgO is added 2) To oxidize HI & stop backward reaction

• Iodination of alkane is a reversible reaction.
• Hydrogen iodide (HI) is formed as a by-product of the reaction.
• As the concentration of HI increases, the forward reaction comes to halt according to Le Chatelier`s principle.
• HgO added being a good oxidizing agent oxidizes HI to I₂.
• The forward reaction is thus favored.
