Best Answer

Molecular substances are substances composed of molecules, which are formed by the combination of atoms through covalent bonds.

The classification of the substances as molecular or ionic is as follows:

Molecular: Glucose, Water, Chlorine, Methane, Ammonia, Copper sulfide

Ionic: Calcium oxide, Silver nitrate, Potassium chloride, Barium sulfate, Sodium hydroxide.

In a molecular substance, atoms share electrons to form stable molecular structures. Unlike ionic compounds, where ions are held together by electrostatic forces, molecular substances have atoms held together within a molecule by covalent bonding.

These substances tend to have lower melting and boiling points compared to ionic compounds. This is because the intermolecular forces between molecules, such as van der Waals forces or hydrogen bonding, are weaker than the strong electrostatic forces between ions. Consequently, molecular substances often exist as gases, liquids, or solids with relatively low melting points.

Molecular substances consist of covalently bonded atoms, whereas ionic substances contain ions held together by electrostatic forces.

Therefore, the classification of the substances as molecular or ionic is as follows:

Molecular: Glucose, Water, Chlorine, Methane, Ammonia, Copper sulfide

Ionic: Calcium oxide, Silver nitrate, Potassium chloride, Barium sulfate, Sodium hydroxide.
