Given information
Which solid in each pair has the higher melting point and why?
Step-by-step explanation
Step 1.
- is an ionic solid
- is a polar molecular solid
Ionic solids have composite units as ions.Hence the force of attraction between the ions is coulombic force of attraction.
Molecular solids are solids whose composite units are molecules. The lattice sites in a crystalline molecular solid are therefore occupied by molecules.And they are held together by the kinds of intermolecular forces—dispersion forces, dipole–dipole forces, and hydrogen bonding.
is a molecular solid with dipole-dipole forces as the intermolecular force of attraction.
