Properties of Ionic vs Covalent Compounds
Ionic and covalent compounds differ in properties because ionic compounds have ions in a lattice, while covalent compounds usually have molecules formed by shared electrons.
Practice This ConceptMain explanation
Teacher explanation
Ionic compounds generally have high melting points due to strong electrostatic attraction between ions. They conduct electricity in molten or aqueous state because ions are mobile. Many covalent compounds have lower melting and boiling points and do not conduct electricity because they have neutral molecules without mobile ions.
Example
Sodium chloride has a high melting point and conducts in solution, while sugar is covalent and does not conduct electricity in solution in the same way.
Simple analogy
Structure first, property next.
Common confusion
Students often memorise one property and apply it to all compounds. The correct property depends on structure and the presence of mobile charged particles.
Exam tip
For comparison answers, write property plus reason: high melting point due to strong ion attraction, conductivity due to mobile ions, and poor conductivity of covalent compounds due to neutral molecules.
