Why do polar covalent molecules have higher melting points than non polar covalent compounds?

They maintain their bonding far longer than nonpolar molecules can with the addition of heat energy. Remember their slightly negative ends will bind with the slightly positive ends of the adjacent molecule.

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
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.
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).
Why do solid compounds have higher melting points than solid covalent compounds?
Solid molecular covalent compounds consist of molecules held together with intermolecular forces, such as dipole dipole interactions and london dispersion forces.Covalent compounds which are giant molecules such as found in diamond or silica are in fact high melting as the strong covalent bonds have to be broken to break down the crystal.Ionic compounds are generally high melting as the strong ionic bonds have to be broken to break down the crystal lattice.

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

Which substance ionic or covalent has a higher melting point?
Generally the ionic molecules has a higher melting point.
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.
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.
Why is the melting point for ionic compounds higher then the melting point of molecular compounds?
Ionic bonds are stronger than covalent bonds and therefore require more energy to break.
Organic compounds are also covalent compounds what properties would you expect organic compounds to have as a result?
They have a higher boiling point and lower melting point and is flamable.
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.
