1.Electronegativity and bonding 

Electronegativity- Ability to attract bonding electrons                                            

 Dipole- Caused by a shift in electron density and difference in electronegativity            

Permanant permanent dipole- Caused by a difference in electronegativity between atoms, means a weak electrostatic attraction forms                                                     

Instantaneous induced dipole- A temporary dipole is caused by a constant movement of elctrons, this can then induce a dipole in a neighbouring atom causing weak attraction      

Hydrogen bonding- Forms…
