Question 4 • IA-Chemistry A Survey of Chemistry A

The melting point of an ionic compound is likely to be a molecular compound.

Answer
A
higher than
B
lower than
C
the same as

Explanation

Ionic compounds have strong electrostatic attractions between positively and negatively charged ions in a crystal lattice. More energy is needed to overcome these attractions during melting than is usually needed to separate molecules, so an ionic compound is likely to have a higher melting point than a molecular compound.
