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

Are melting points of covalent compounds high or low compared to ionic compounds?
Ionic compounds have strong electrostatic force of attraction and hence have higher melting points than covalent 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.
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.
What is the melting point for covalent?
Covalent bonds do not melt. Compounds with covalent bonds melt and the melting point depends primarily on whether there are discrete molecules held together by intermolecular forces (which have lower melting points) or giant covalent networks such as in silica or diamond (which tend to have higher melting points).

How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling 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.

Why do covalent compounds have lower melting points then ionic compounds?
Covalent compounds tend to be negatively charged than an ionic compound.
Why melting point of diamond is higher than that of silicon carbide?
Diamond is a covalent network solid, and those types of compounds have higher melting points than other types of compound.
What kind of solid tends to have the lowest melting points?
Molecular compounds tend to have the lowest melting points.
Compared with the melting points of ionic compounds the melting points of molecular solids tend to be .?
Ionic compounds have a higher melting point.
Do ionic compounds have lower boiling points than polar covalent?
Ionic compounds have higher boiling points than covalent compounds.
