What is an example of a polarity of bonds practice problem?
A possible example would be: Is water and
To answer this the Lewis Structures should be drawn and from this the molecular geometry can be obtained to then tell you if it is polar or non-polar.
Water has a bent tetrahedral geometry which is four bonding sites (two lone pairs of electrons, two Hydrogen atoms) so therefore the dipole moment of water is greater than zero because of the reason in brackets.
So to conclude a molecule which has a dipole moment of zero is non-polar and a molecule which has a dipole moment greater than zero is polar.
Hope I helped answer your question :)
