Question

Why do covalent compounds have low melting and boiling points?

Answer 1

the fore of attraction between the bonds are very weak as it is made from sharing of electrons 

very less energy is sufficient to break these bonds


therefore covalent have low melting and boiling point.

Answer 2

Answer:

Covalent compounds have low melting and boiling points because they are made up of electrically neutral molecules. So, the force of attraction between the molecules of a covalent compound is very weak.

Explanation:

Only a small amount of heat energy is required to break these weak molecular forces. That is why covalent compound have low melting boiling points.

hope it's help u....
