Ionic compounds generally have a higher melting point. This is because the bonds between the negative and positive ions are strong, and this keeps the solid together as the temperature rises. Covalent compounds have comparatively weak bonds between the molecules, so as the temperature rises, these bonds are broken easily and the substance turns into a liquid.

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.
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.
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?
Ionic (e.g. sodium chloride etc.): highmelting/boiling points. Ionic bonds (electrostatic attraction between oppositely charged ions) must be broken to break the ionic lattice and form a liquid/gas. Ionic bonds are strong so lots of energy is required.Giant covalent (e.g. diamond, graphite, silicon dioxide): high melting/boiling points. Covalent bonds (shared pairs of electrons) must be broken for the substance to become a liquid/gas. Covalent bonds are strong so lots of energy is required.Simple covalent (e.g. water, hydrogen, ammonia, bromine): low melting/boiling points. Although covalent bonds are strong, they do not need to be broken in order to separate molecules and the substance become a liquid/gas. Only weak forces between the molecules must be overcome, which does not require much energy.
Which substance ionic or covalent has a higher melting point?
Ionic substances generally have higher melting points compared to covalent substances. This is because ionic bonds are stronger and involve the attraction between oppositely charged ions, requiring more energy to break compared to the sharing of electrons in covalent bonds.
How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling points.

Why an ionic bonds have higher melting than a covalent bonds?
The ionic bond is stronger.

What are the effects of covalent and ionic substances?
well ionic substances are solid at room temperature,they are generally soluble in water ,they have high melting and boiling points,while covalent substances are generally liquid and gases at room temperature,non-polar covalent substances are generally insoluble in water while polar covalent are generally soluble in water
what has higher melting points ionic or covalent compounds?
Ionic compounds have higher melting points because the bond olding the ionic crystal together is stronger than the intermolecular forces (van der Waals) holding covalent molecules together. Giant covalent molecules such as dialmond and silicon dioxide have very high melting points because the lattice is held together by stong 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.
Who has higher melting points ionic compounds or covalent compounds?
Ionic compounds have higher melting points than covalent compounds. Common table salt, sodium chloride, is an ionic compound and has a melting point of 801 oC. Table sugar, sucrose, a covalent compound, has a melting point of about 186 oC.
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.
