Give all the tests to distinguish chloroethane from other organic compounds.

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.
