Bonding within a molecule is:
Ionic and covalent bonding
Two types of intramolecular bonding
This involves the transfer of one or more e- between a metal and a non-metal
change in E.N. that is >1.7 demonstrates:
This involves the sharing of e- between two non-metals
atoms have the same E.N. and the bond is non-polar (i.e.. O2)
Equal sharing or polar bonds is when:
atoms have different E.N. and the bond is polar
Unequal sharing or polar-covalent bonds is when:
change in E.N. between 0.5-1.7
-molecular shape (symmetry)
-the presence of polar bonds
Molecular Polarity depends on:
1.7-3.3 difference in E.N. is this type of bond
Bonding between molecules that are weaker then intramolecular bonds:
London dispersion forces
temporary bonds between all molecules caused by the constant movement of e-'s and temporary charge imbalances
Dipole - Dipole
this happens only between polar molecules they are held together due to partial charges they are stronger then L-D forces
this happens only between polar molecules it is the strongest of the three it induces strong h-bonds between nearby molecules
