Question

Nacl solution give white with agno3 but ccl4 does not

Answer 1

This happens because NaCl is IONIC in nature and hence furnishes ions Na+ and Cl- in the solution and thereby forming a white precipitate with AgNO3 i.e. AgCl. However, CCl4 is COVALENT and that is why does not furnish ions and hence does not form any precipitate.
