Why do covalent compounds and ionic compounds have different melting points?
Melting points are a reflection of the intermolecular forces and intramolecular forces of the compound. The stronger the intermolecular force, the more energy it takes to bring it to a different state.
Ionic compounds have high melting points because a lot of energy is needed to break the bonds between the ions.?
In general, yes.
Why do ionic compounds have high melting points?
In ionic compounds, there are strong attractions among the ions; therefore it takes a lot of energy to break those bonds.High melting point depends on bond strength. When talking about bond strength in ionic compounds, I mean lattice energy. So the easiest answer is: They have a high lattice energy.The strong electrostatic interactions between ions require a lot of energy to break the bonds.
Why is the melting point for ionic compounds higher then the melting point of molecular compounds?
Ionic compounds have strong electrostatic forces of attraction between oppositely charged ions, which require more energy to overcome compared to the weaker intermolecular forces in molecular compounds. This results in higher melting points for ionic compounds.
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.

Why do electrovalent compounds have high melting and boiling points?
Electrovalent compounds have high melting and boiling points because they have strong electrostatic forces of attraction between the positively charged metal ions and negatively charged non-metal ions. These forces require a significant amount of energy to overcome, resulting in high melting and boiling points for these compounds.
How do ionic compounds and molecular compounds differ in their relative melting and bioling points?
Ionic compounds tend to have higher melting and boiling points compared to molecular compounds. This is because ionic bonds are generally stronger than the intermolecular forces present in molecular compounds, such as van der Waals forces. The strong electrostatic forces between ions in an ionic compound require more energy to overcome, leading to higher melting and boiling points.
Which type of compound has the lower melting points - ionic or molecular Why?
The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the inter molecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound.
Why does ionic solids have higher melting points compared to molecular solids?
The melting and boiling points of molecular compounds are generally quite low compared to those of ionic compounds. This is because the energy required to disrupt the intermolecular forces between molecules is far less than the energy required to break the ionic bonds in a crystalline ionic compound
Why do solid ionic compounds have high melting points?
Ionic compounds have strong bonds holding the crystal lattice together that are due to the attraction between the oppositely charged cations and anions. Covalent compounds which are made up of discrete molecules (not giant molecular compounds like silica) have only weak intermolecular forces holding the solid form together and therefore these solids are easier to "break up" with thermal energy. t.
When are ionic compounds at melting point?
Ionic compounds typically have high melting points because the electrostatic forces holding the ions together are strong, requiring a lot of energy to break the bonds. As a result, ionic compounds usually melt at high temperatures, often above 500°C.
Are melting points of covalent compounds high or low compared to ionic compounds?
Melting points of covalent compounds are generally lower than those of ionic compounds. This is because covalent compounds have weaker intermolecular forces compared to the strong electrostatic forces present in ionic compounds, so they require less energy to break apart the molecules.
