Question

1. covalent substances generally have lower melting points than ionic substances. which analysis correctly explains these properties?

Explanation:

Ionic substances have ionic bonds formed by the transfer of electrons between atoms, creating strong electrostatic attractions. Covalent substances have intermolecular forces which are weaker. Stronger bonds in ionic substances require more energy to break, resulting in higher melting - points. So, ionic bonds are stronger than intermolecular forces in covalent substances.

Answer:

Ionic bonds are stronger than intermolecular forces in covalent substances.
