Iodoform gives precipitate with silver nitrate but chloroform does not. Explain.

Answer»

C - I bond is much weaker than C - Cl bond. Therefore, when CHI3 is heated it gives I- ions which give a yellow precipitate of AgI when treated with AgNO3 solution. On the other hand C - Cl bond of CHCl3 does not break on heating to give Cl- ions and hence precipitate of AgCl is not formed when treated with AgNO3 solution.
