What causes the differences in melting points and boiling points between ionic and covalent compounds molecular substances?
The differences in melting and boiling points between ionic and covalent compounds are due to the strength of the intermolecular forces present. Ionic compounds have strong electrostatic forces of attraction between oppositely charged ions, resulting in higher melting and boiling points. Covalent compounds have weaker intermolecular forces such as London dispersion forces or dipole-dipole interactions, leading to lower melting and boiling points compared to ionic compounds.
Do covalent compounds have lower boiling point than ionic compounds?
In general, covalent compounds have lower boiling points than ionic compounds. This is because covalent compounds have weaker intermolecular forces compared to the strong electrostatic forces between ions in ionic compounds. As a result, less energy is required to overcome the intermolecular forces in covalent compounds, leading to lower boiling points.
Write down the differences between ionic compound from covalent compounds?
Ionic Compounds are formed by complete transfer of electrons while Covalent compounds are formed by sharing of electrons. Ionic compounds have higher melting points while covalent compounds have lower.
How are ionic and covalent compounds different in terms of melting and boiling point and electrical conductivity and hardness and brittleness?
Ionic compounds generally have higher melting and boiling points.
Why the melting and boiling point of covalent compound are low?
Compared to ionic compounds, covalent compounds have relatively low melting and boiling points because covalent bonds are not as strong as ionic bonds, and it is the bonds which hold materials together in the solid, or more solid phases.
How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling points.

Why do molecular compounds have low melting points and low boiling points relative to ionic substance's?
The melting points and boiling points of molecular covalent compounds (ones with discrete molecules) are lower than ionic solids and giant molecule covalent compounds like (silica, SiO2) because the forces that attract them together in the solid and the liquid states (van der waals, hydrogen bonding and dispersion forces) are weaker than ionic (or covalent) bonds.
Why the melting and boiling point of covalent compound are low?
Compared to ionic compounds, covalent compounds have relatively low melting and boiling points because covalent bonds are not as strong as ionic bonds, and it is the bonds which hold materials together in the solid, or more solid phases.
What is true about all covalent compounds?
Covalent compounds involve the sharing of electrons between atoms. They tend to have lower melting and boiling points compared to ionic compounds. Covalent compounds are often formed between nonmetal atoms.
What is the conclusion of the properties of ionic and covalent compounds?
Ionic compounds result from the transfer of electrons between atoms leading to the formation of ions, while covalent compounds form from the sharing of electrons. Ionic compounds tend to have higher melting and boiling points compared to covalent compounds due to the stronger electrostatic forces between ions.
Why do covalent compounds have lower melting points then ionic compounds?
Covalent compounds have lower melting points compared to ionic compounds because covalent bonds are generally weaker than ionic bonds. In covalent compounds, individual molecules or atoms are held together by shared electrons, which are weaker than the electrostatic attraction in ionic compounds. Hence, less energy is required to break the bonds in covalent compounds, resulting in lower melting points.
What temperature do ionic compounds boil?
Ionic compounds do not have a specific boiling temperature as it depends on the specific compound. The boiling point of an ionic compound will generally be higher than that of covalent compounds due to the strong electrostatic forces between the ions.
Do Covalent compounds boil at higher temperatures than ionic bonds or lower temperatures than ionic bonds?
'Covalently bonded' = 'Non polar' compounds have much LOWER boiling points than polar compounds and 'ion bonded' = 'Crystallic' compounds.(Compare: (all at STP)H2S (gas, linear, covalent H-S bonds) andH2O (liquid, non-linear, polar H-O bonds) andNa2O (solid, ionic, crystal, tetrahedrical(Na+) +cubic(O2-)
