Electronegativity is the ability to attract the bonding electrons in a covalent
bond
Atoms with strong electron pulling power in covalent bonds are said to be highly
electronegative.
Fluorine is the most electronegative element. Oxygen, nitrogen chlorine are also
strongly electronegative.
In a covalent bond between two atoms of different…

Whether a molecule has a permanent dipole depends on its shape and the polarity of its
bonds.
1. In a simple molecule, like hydrogen bromide, the polar bond gives the whole
molecule a permanent dipole ­ it's a polar molecule.
2. A more complicated molecule may have several polar bonds.…

Intermolecular forces are forces between molecules. They are much weaker than
covalent, ionic or metallic bonds.
Permanent Dipole ­ Permanent Dipole
Permanent dipoles occur when a molecule has two atoms bonded together which have
substantially different electronegativities so that one atom attracts the shared electrons
much more than the other.…

Glycerol Triester
Fatty Acids
Fatty acids are the carboxylic acids in fats and oils. They have an even number of
carbons in their unbranched
carbon chain. These chains can either be saturated or unsaturated.
Any natural oil or fat contains a mixture of triesters. Triesters from largely saturated fatty
acids…
