Concept explainers
Interpretation: The different in salt and sugar despite being crystalline solids needs to be explained.
Concept introduction: A crystalline solid characterized by regular arrangement of its components. There are many types of crystalline solids such as ionic solids, molecular solids, covalent network solids, and metallic solids.
Answer to Problem 1RQ
The difference between salt and sugar arises because former is ionic solid and later is molecular solid.
Explanation of Solution
Common salt (
On the contrary, sugar is a molecular solid. In a molecular solid molecules are held by intermolecular forces like dipole-dipole, London dispersion force and hydrogen bonding.
Sugar consists of neutral molecules (
The difference between salt and sugar arises because former is ionic solid and later is molecular solid.
