Question

The solution of one of the following compounds will not conduct electricity. This compound is:

विकल्प

• NaCl

• CCl₄

• MgCl₂

• CaCl₂

Answer 1

CCl₄

Explanation:

Carbon tetrachloride (CCl4) is a covalent compound consisting of neutral molecules, whereas NaCl, MgCl₂, and CaCl₂ are all ionic compounds. When ionic compounds dissolve, they break apart into free-moving charged ions that easily carry an electric current. Since CCl₄ does not contain or form any mobile ions, its solution is completely unable to conduct electricity.
