Question

Why covalent bond does not conduct electricity ?

Answer 1

A covalent bond is formed between non metal atoms, which combine together by sharing electrons. Covalent compounds have no free electrons and no ions that conduct electricity .so they don't conduct electricity.

An ionic compound consists of ions held by strong forces in the solid state. But when an ionic compound dissolves in water to form a solution, the constituent ions get separated and they disperse across the solution. This helps in conducting an electric current through the solution.
