Question

Intermolecular forces do not exist in ionic compounds. Justify the statement.

Answer 1

1. Ionic compounds: These are the compounds in which electron transfer takes place between two atoms where one atom loses electrons to form cation and the other atom gains electrons to form anion.
2. Covalent compounds: These are the compounds in which sharing of electrons takes place between atoms to form molecules.
3. In ionic compounds there will be attractions between ions so there will be attractions between large number of individual ions Where as covalent bonds are formed due to sharing of electrons which forms a molecule and molecules have attractions between them called as Van der Waals forces.
4. Hence, intermolecular forces exist between covalent molecules only.
