Crystalline Solids
Created @January 20, 2025 9:08 PM
Class Pharmaceutical Chemistry
Forces
In solids it ranges from v.small to very large
Ions, atoms or molecules are bound together via attractive forces e.g
intermolecular forces, metallic bonding, covalent bonding, ionic
interactions
Molecular Solids
Molecules of raw materials are bound by intermolecular forces
These forces can be dispersion, dipolar, H bonding or a mixture
Lots of bigger molecules have enough dispersion forces to be solids at
room temp
Molecular solids are held via intermolecular forces and have low melting
points
Benzoic acid crystals have molecule pairs held using H bonds, when the
pairs stack it’s held together using dispersion forces
Network Solids
Have high melting points
Bonding patterns decides its properties
Diamond is held together using covalent bonds
