Carbon tetrachloride CCl4 (a non polar molecule), has a normal boiling point of 76.7 C while methanol CH3OH (a very polar molecule), has a somewhat lower normal boiling point of 65 C. Offer a possible explanation for this difference in boiling points based on the different types of intermolecular forces present in the two liquids.
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.
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
A molecule which contains polar bonds will always have a net dipole moment greater than zero. True False
How can a molecule have polar bonds yet have a dipole moment of zero? Given an example.

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
