1. Covalent Bonding: Molecular compounds are formed by the sharing of electrons between atoms. This sharing creates covalent bonds, which are strong but less strong than the ionic bonds found in ionic compounds.
2. Low Melting and Boiling Points: Generally, molecular compounds have lower melting and boiling points than ionic compounds. This is because the intermolecular forces (forces between molecules) are weaker than the electrostatic attractions between ions in ionic compounds.
