what happens to chloroform on warming with silver? |
Hexachloroethane Acetylene Ethylene Carbon |
Acetylene |
The correct answer is (2) Acetylene. When chloroform is warmed with silver powder, it undergoes a reaction called the Carius reduction. In this reaction, the chlorine atoms in the chloroform are replaced by hydrogen atoms, forming acetylene. The chemical equation for the reaction is:
Acetylene is a colorless, flammable gas with a garlic-like odor. It is used in a variety of applications, including welding, lighting, and the production of plastics. The other options are incorrect. Option (1), Hexachloroethane, is a colorless, odorless liquid that is used as a solvent and fumigant. Option (3), Ethylene, is a colorless, odorless gas that is used in the production of plastics and other chemicals. Option (4), Carbon, is a black, non-metallic element that is the most abundant element on Earth. |
