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.
What else can I help you with?
Molecular compounds that dissolve in water do not conduct electricity because no?
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.
Can inorganic compounds dissolved in water conduct electricity?
yes
What conducts electricity when dissolve in water?
Ionic compounds conduct electricity when dissolved in water.
True or false Low melting points and lack of eletrical conductivity are properties of molecular compounds?
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.
Why compounds formed from non metals normally do not conduct electricity?
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.
Why can ionic compounds conduct electricity but molecular compounds usually can not?
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.
Molecular compounds do not conduct electricity because they?
do not break up into ions.
What are the properties of molecular compound?
Molecular compounds generally do not conduct electricity and have low melting points.
Why don't molecular compounds dissolved in water conduct electricity?
There are no ions present
Which is a property shares by most molecular compounds?
Most molecular compounds have a low melting point. They also typically don't conduct electricity.
Why don't covalent molecular compounds 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.
Why do molecular compounds not conduct electricity?
do not break up into ions.
Which is a property shared by most molecular?
Most molecular compounds have a low melting point. They also typically don't conduct electricity.
Molecular compounds that dissolve in water do not conduct electricity because no?
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.
Molecular compuonds that dissolve in water do not conduct electricity because no charged ions present?
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.
Do ionic compounds and molecular compounds behave similarly when they are dissolved?
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.
Describe properties that would help you to distinguish an ionic compound from a molecular compound.?
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.
