When do covalent compounds

conduct electricity?

Conditions for conducting electricity are free

electrons that can move throughout the

structure and carry a charge. In covalent

compounds, there are no free electrons. Most

covalent compounds that dissolve in water

form solutions have uncharged molecules.

For example, sugar is a covalent compound

that dissolves in water but does not form ions.

However, acids form ions when they dissolve

in water. Thus they conduct

electricity.
