Question

iodoform gives precipitate with silver nitrate on heating but chloroform does not. why?

Answer 1

iodoform + AgNO3 = AgI which has low sloubility product and seen as precipitate
 chloroform + AgNO3 = AgCl which is slouable and no precipitate is seen

Answer 2

The reaction of Iodoform and Chloroform with silver nitrate

Explanation

• The compound such as iodoform and chloroform produces the different product when they react with silver nitrate.
• The chemical reaction occurring between in Iodoform and silver nitrate is as shown:

$AgNO_3+CHI_3\rightarrow AgI+CHCl_2+NO_3^{-}$

• The reason for precipitation is the formation of $AgI$, as it is least soluble in the solution on heating.
• The reaction occurring between silver nitrate and chloroform is as shown:

$AgNO_3+CHCl_3\rightarrow AgCl+CHCl_2+NO_3^{-1}$

• $AgCl$ readily gets soluble in aqueous solution on heating and doesnt not gets precipitated.
