Molecular compounds are charge neutral. Molecular compounds dissolve in water as individual molecules. For example if 1.0g of C12H22011 (sucrose or table sugar) dissolves in water the solid will become many individual C12H22011 molecules floating in water but will remain charge neutral. Therefore, this solution does not conduct electricity. This is known as a nonelectrolyte solution.
On the other hand, when ionic compounds, like NaCl (table salt), are dissolved in solution they break up into individual ions. In this case Na+ and Cl-. These ions with their respective charges make the solution electrically conductive. This is called an electrolyte solution.
They do not conduct electricity because they do not dissociate into ions in water to carry an electric charge. Ionic compounds, on the other hand, dissociate into ions in water and can conduct electricity.
yes
Ionic compounds conduct electricity when dissolved in water.
True. Molecular compounds have low melting points because their intermolecular forces are weaker compared to ionic or metallic compounds. They also do not conduct electricity well because they lack free-moving charged particles.
Compounds formed from nonmetals do not conduct electricity because nonmetals typically do not have free-moving electrons that can carry an electric current. In these compounds, the electrons are held tightly by the atoms, preventing them from moving freely to conduct electricity.
Ionic compounds can conduct electricity because the ions in the solid state can move and carry electric charge. In contrast, molecular compounds usually do not conduct electricity because they do not dissociate into ions in solution or in the solid state, resulting in no free charge carriers to conduct electricity.
do not break up into ions.
Molecular compounds generally do not conduct electricity and have low melting points.
There are no ions present
Most molecular compounds have a low melting point. They also typically don't conduct electricity.
Covalent substances do not conduct electricity because they are sharing electrons, hence they are in a fixed position and are not able to move around and contribute to movement of the electric current.

That's correct. Molecular compounds do not dissociate into ions in solution, so they do not conduct electricity as there are no free charged particles to carry the current.
Ionic compounds eg NaCl yield ions when dissolved in water, NaCl (in water) -> Na positive ions and negative Cl ions. Ions have electrical charges & conduct electricity. All compounds are "molecular", ie they are made up of more than one atom in combination. Some molecules are not ionic, eg common sugar, and when they are dissolved in water they do not yield ions and do not conduct electricity.
Ionic compounds typically have higher melting and boiling points compared to molecular compounds due to the strong electrostatic forces between oppositely charged ions. Ionic compounds are typically soluble in water and conduct electricity when dissolved or in molten state, whereas molecular compounds are often insoluble in water and do not conduct electricity in any state.
