Covalent compounds are formed by the sharing of electrons. So, it is important to note that these compounds have a weak inter-molecular force. In other words, their bond is not strong as the force between their molecules is not very strong. So, it is easier to break the bonds between element. Melting or boiling or nay phase change in general is accomplished when the bonds holding the atoms together is broken.
Thus, as covalent compounds have a weak bond strength, they can be broken very easily and that is why they have low melting and boiling points.

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.
Which solid is more likely to have the lowest melting point an ionic solid or molecular solid?
Molecular Solids have a lower melting point
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.
What usually has a lower melting points than the ionic solids?
Covalent compounds have a lower melting point.
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.

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

CaCl2 is ionic, is solid and will have the highest melting point. The rest are covalent compounds.
What usually has a lower melting points than the ionic solids?
Covalent compounds have a lower melting point.
Is the boiling point of covalent compounds high or low?
high boiling point low 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.
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.
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.
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.
