A molecule which contains polar bonds will always have a net dipole moment greater than zero.
True
False
This statement is not true as a molecule which has a polar bond will always have a net dipole moment. This depends on the direction of the bonds. They may cancel out each other if the polarity is in opposite direction. For example C-Cl bond are polar but CCl2=CCl2 is not nonpolar compound due to canceled dipole moment of C-Cl bond in opposite direction. An example is given in the above attachment.
A molecule which contains polar bonds will always have a net dipole moment greater than zero
A CO2 molecule contains two polar bonds, but the net dipole moment is zero. It is because (a) the molecule has symmetrical linear geometry and dipole moments cancel out each other (b) the molecule is non-linear (c) the electronegativity difference between the two atoms is too large (d) the electronegativity difference between the two atoms is too small
How can a molecule have polar bonds yet have a dipole moment of zero? Given an example.
Is it possible for a molecule to have no polar bonds and a net dipole? Which of the molecules, if any, have no polar bonds and a net dipole?
Explain why carbon tetrachloride is a non polar (has a net zero dipole moment) molecule while chloroform is polar molecule.
Determine if the OCS molecule is polar or non-polar. Draw in the net dipole moment. I am confused on how to determine the directions of the dipole arrows.

4. Among BeF2, BF3, NH3 and CCI4, the molecule with net dipole moment (polar) is: (you need to know the Lewis structure of those molecules) a) BeF2 b) BF3 C) NH3 d) CCI4 5. According to VSEPR theory, (a) the non-bonding electron pairs (lone pairs) only decide the structure of the molecule (b) the bonding pairs only decide the structure of the molecule (c) the lone pairs and bonding pairs both decide the structure of the molecule (d) none of these
