Because have lower melting points and boiling points
Molecular compounds generally do not conduct electricity and have low melting points.
Ionic compounds have higher melting and boiling points than molecular compounds due to the strong electrostatic forces between ions. Ionic compounds are usually solid at room temperature, while molecular compounds can be solid, liquid, or gas. Ionic compounds conduct electricity when dissolved in water, while molecular compounds do not.
Molecular (covalent) compounds are not dissociated in water.
Ionic compounds typically have higher melting and boiling points compared to molecular compounds, due to the strong electrostatic forces between ions in the crystal lattice. Ionic compounds also tend to conduct electricity when dissolved in water or in molten state, while molecular compounds do not conduct electricity in either state. Additionally, ionic compounds are often composed of a metal and a nonmetal, whereas molecular compounds are composed of nonmetals.
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.
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.
they will not ionize
Most molecular compounds have a low melting point. They also typically don't 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.
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.
do not break up into ions.
Molecular compounds are formed by sharing electrons between atoms, leading to the formation of covalent bonds. They do not conduct electricity in their solid form because they do not contain free ions. Molecular compounds typically have lower melting and boiling points compared to ionic compounds.
