Because have lower melting points and boiling points
Molecular compounds generally do not conduct electricity and have low melting points.
Molecular (covalent) compounds are not dissociated in water.
strengths of attraction between the particles in the compounds
Most molecular compounds do not conduct electricity and have low melting points.
they will not ionize
Ionic compounds conduct electricity while molecular compounds do not
Most molecular compounds have a low melting point. They also typically don't conduct electricity.
do not break up into ions.
t Answer Well firstly, ionic compounds form from metals bonding with non metals. Molecular/covalent form from non metals bonding with non metals. A strong electrostatic force between ionic compounds results in them having high melting points. A weaker electrostatic force between molecular compounds results in them having lower melting points and thus weaker bonds. Ionic compounds are made up of ions, so will conduct electricity. Covalent compounds only share electrons and so are not ions, and will not conduct electricity.
There are no ions present
Aqueous [note spelling] solutions of ionic compounds conduct electricity, but aqueous solutions of molecular compounds do not, unless the molecular compounds dissociate into ions when dissolved. Sugar, acetone, ethanol, and methanol, for example, do not dissociate, but acetic acid does.
