POLARITY OF MOLECULES
Polarity refers to having
a dipole, that is, a positive
and a negative end.
Polarity of Molecules
dipole is a pair of equal and
oppositely charged or magnetized
poles

POLARITY OF MOLECULES
Polarity is dictated by
the distribution of electrons
in the molecule; either the
electrons are equally
distributed or unevenly
scattered throughout the
molecule.

POLARITY OF MOLECULES
Polarity is a physical
aspect of a molecule that
affects and influences the
behavior of a molecule.
Generally, the polarity of a
molecule can be predicted
from its shape.

the bond's dipole moments
is not zero.

When electrons in a
polar covalent bond are
unequally shared between
two bonded atoms, it
causes partial positive and
negative charges.

POLAR BOND
Polarity of Molecules
A polar bond is a type
of covalent bond. A bond
between two or more atoms
is polar if the atoms have
significantly different
electronegativities (>0.4).

POLARITY OF MOLECULES
POLAR BOND
Polarity of Molecules
Polar bonds do not
share electrons equally,
meaning the negative
charge from the electrons is
not evenly distributed in the
molecule.

POLAR BOND
Polarity of Molecules
A classic example of a polar bond
is the bond in water between hydrogen
and oxygen. The bond is classified as a
polar bond because it has a large
electronegativity difference of 1.4. The
electrons in hydrogen are more
attracted to the electrons in oxygen
because oxygen is more
electronegative.

also a type of covalent
bond. Unlike polar bonds,
non-polar bonds share
electrons equally.

NON-POLAR BOND
Polarity of Molecules
An example of a non-polar
bond is the bond in chlorine.
Chlorine contains two chlorine
atoms. The electrons are
shared equally because the
electronegativity difference
between the two atoms is zero.

POLARITY OF MOLECULES
DIPOLE MOMENT
Polarity of Molecules
In more complex molecular
shapes, if the dipole moments do
not add up to zero or do not cancel
out, a net dipole moment is
present, making the molecule
polar. A polar molecule results
when a molecule contains polar
bonds in an asymmetrical
arrangement.

It is a quantity that
describes the polarity of a

measure the amount of polarity
of a molecule, the result is
called the dipole moment.
