Expert Answer:
Test to distinguish between chloroethane and bromoethane:
Add small amount of KOH and acidify with dil. Nitric acid and then few drops of silver nitrate solution.
A white ppt. Soluble in NH4OH indicates chloroethane while a light yellow ppt. partially soluble in NH4OH indicates bromoethane.
C2H5Cl + KOH → C2H5OH + KCl
KCl + AgNO3 → AgCl(White ppt.)
C2H5Br + KOH → C2H5OH + K Br
K Br + AgNO3 → Ag Br (Pale yellow ppt.)
Test to distinguish between chloroethane and vinyl chloride:
Ethyl chloride will react with AgNO3 to give a white ppt. of AgCl, whereas vinyl chloride will not respond to this test.
