Compared to ionic compounds, ____ generally have lower melting points and boiling points
|
elemental
|
|
bonded
|
|
double-bonded
|
|
covalent
|
Explanation:
Detailed explanation-1: -The molecules of covalent compounds are held by weak intramolecular forces. Thus, a very small amount of energy is required to break the bonds between two or more molecules. That is why they have low melting and boiling points.
Detailed explanation-2: -Ionic compounds have high melting and boiling points while covalent compounds have low melting and boiling points.
Detailed explanation-3: -Being held by a strong electrostatic force of attraction between ions, ionic compounds have high melting and boiling points.
