(a)
Interpretation:
From the given pair of ionic compounds
Concept introduction:
The melting point of a substance is the temperature at which it changes from solid state to liquid at atmospheric pressure.
Ionic compound have more melting point because ionic bond is very strong.
Covalent compound have less melting point because covalent bond is weak than compared to ionic bond.
(b)
Interpretation:
From the given pair of compounds
Concept introduction:
Factor that determine melting point of a compound.
The melting point of a substance is the temperature at which it changes state from solid to liquid at atmospheric pressure is called as melting point.
Ionic compound have more melting point because ionic bond is very strong.
Covalent compound have less melting point because covalent bond is weak than compared to ionic bond.
