( iii) Hydrogen Bonded Molecular Solid s:
o
o
o
Hydrogen Bonded Molecular Solids contain polar covalent bonds between H and F, O or N atoms.
Strong hydrogen bonding binds molecules of such solids like H2O( ice).
They are non-conductors of electricity and are volatile liquids or soft solids under room temperature and pressure.
Ionic Solids o The constituent particles of these solids are ions.
o
The solid is composed of three dimensional arrangements of cations and anions that are bonded by strong coulombic( electrostatic) forces.
