Ch 29: Intermolecular forces
H bond
G V VI VII increase
HF, H2O and NH3
H bond (strong)
FON-H - - - -FON
Lone pair on FON
Lone pair = H bond / mol
Van der Waals' forces
Permanent dipole
Polar
Electronegativity
Polar covalent bond
Unequal sharing of bonding e-
+ve end attract -ve end
In crystalline solid
Permanent dipoles line up opp charge
Induce
Induced dipole
Instantaneous dipole
All
Continually changing dipole (mol/atoms)
e- cloud may not be perfectly symmetrical
Induce
Dipole-dipole attractions
Polarity
Mol size
Not RAM
e- cloud distort
Shape/ surface area
Stronger -> MOAR energy to separate atoms
B.p. Of G 4
Decrease with mol size
Mix
Temp V
IntM F V
Covalent
