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
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 compounds will have the highest melting point CO2 CaCl2 N2H4 or SCl6?
CaCl2 is ionic, is solid and will have the highest melting point. The rest are covalent compounds.
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.
Is Ionic bond have higher melting and boiling point than covalent bond?
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.
Why an ionic bonds have higher melting than a covalent bonds?
The ionic bond is stronger.
How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling points.
Are melting points of molecular substances higher than those of ionic substance?
Ionic substances have higher melting points.

What information would the melting point give you in terms of the bonding of a compound?
Ionic compounds have melting points higher than covalent 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.
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.
Why silve iodideAgI a compound used in photography has much higher melting point than vanillin c8h8O3 a sweet smelling compound used in flavorings?
Silver iodide (AgI) is an ionic compound with strong attractions between oppositely charged ions, resulting in a higher melting point. Vanillin (C8H8O3) is a covalent compound with weaker intermolecular forces, leading to a lower melting point. Ionic compounds typically have higher melting points compared to covalent compounds due to their stronger bonding interactions.
