because covalent compounds form distinct molecules, in which the atoms are bound tightly to one another. Unlike in ionic compounds, these molecules don't interact with each other much (except through relatively weak forces called "intermolecular forces"), making them very easy to pull apart from each other. Since they're easy to separate, covalent compounds have low melting and boiling points.

Do non polar covalent compounds have high or low melting points?

No they have high melting and boiling points. Don't get confused with simple molecular structures such as water and carbon dioxide which have simple covalent structures. When you heat them you are overcoming the forces BETWEEN THE MOLECULES (intermolecular/van der waals forces of attraction), NOT the actual covalent bonds themselves, like the bond betwen the C and either O in carbon dioxide.


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 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.


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 the covalent melting and boiling point high or low?

The covalent melting and boiling points are generally lower than those of ionic compounds due to weaker intermolecular forces between covalent molecules. These forces include London dispersion forces, dipole-dipole interactions, and hydrogen bonding. The actual melting and boiling points vary depending on the specific molecules involved.

What properties do most covalent compounds have in common?

Most covalent compounds have relatively low melting and boiling points, as they are held together by weak intermolecular forces. They are usually insoluble in water but soluble in nonpolar solvents. Covalent compounds tend to be nonconductors of electricity in their solid form.


Why do molecular compounds have low melting points?

The covalent bond is not so strong as the ionic bond.

Which type of compound would have the lowest melting point?

Compounds bonded by covalent bonds do not necessarily have low melting points. Some have whereas some don't have.Some polymers and hydrocarbons have very high melting points. But it can be said that they don't have melting points as high as ionic compounds. It is so because ionic bonds are stronger than the covalent bonds.

List properties common to many organic compounds?

Some common properties of organic compounds include having covalent bonds, containing carbon and hydrogen atoms, being flammable, having low melting and boiling points, and often having a complex molecular structure.


Why do molecular compounds have low melting points and low boiling points relative to ionic substance's?

The melting points and boiling points of molecular covalent compounds (ones with discrete molecules) are lower than ionic solids and giant molecule covalent compounds like (silica, SiO2) because the forces that attract them together in the solid and the liquid states (van der waals, hydrogen bonding and dispersion forces) are weaker than ionic (or covalent) bonds.
