Why dont molecular compounds conduct electricity when dissolves in water?
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.
Why is it that only molecular compounds can have a molecular formula?
Because there are no compounds that aren't molecules/molecular. The question as posed is nonsense. Rephrase?
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.
What type of compound will not dissolve in water?
A) nonpolar compounds will not dissolve in water because water is polar
Why gasoline can dissolve sticky stuff?
Allot of sticky stiff is made form organic compounds (compounds made mostly out of Carbon). Many organic compounds repel water and thus can not be dissolved in water, to dissolve them you therefore need an organic liquid such as gasoline.
How can water dissolve some ionic compounds as well as some molecular compounds?
Water can dissolve some ionic compounds as well as some molecular compounds because of its polarity. It is polar enough to dissolve ionic compounds into their ions. Water does not dissolve molecular compounds by breaking covalent bonds, but through intermolecular forces.
Is it true or false molecular compounds that dissolve in water do not conduct electricity because no charged ions are present?
True. Molecular compounds that dissolve in water do not conduct electricity because they do not dissociate into charged ions when dissolved. Since they do not produce free ions that can carry an electric current, they are unable to conduct electricity in aqueous solutions.
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.
Molecular compounds do not conduct electricity because they?
do not break up into ions.
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.
Discuss how water can dissolve a molecular compond?
Water dissolves some molecular compounds because water is a polar molecule.
Why do molecular compounds not conduct electricity?
do not break up into ions.
How are the properties of molecular compounds poor conducters of electricity?
Because have lower melting points and boiling points

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.
Ionic compounds that dissolve in water conduct electricity because they break into gases that move freely.?
Ionic compounds dissolve in water into their constituent ions, which are charged particles that allow the flow of electricity. When an electric current is applied, these charged ions are able to move freely through the solution, facilitating the conduction of electricity.
