Is a dipole polar or nonpolar?
Nonpolar compounds do not have dipole moments. Dipole moments are polar forces. If the compound is nonpolar then there is no polarity within that molecule.
Mathematically why do the dipole moments cancel in a carbon tetrachloride molecule?
Carbon tetrachloride is tetrahedron shaped, it is 100% symmetrical. Thus all the 4 bond dipole moments cancel each other and the net dipole moment is zero.
Is CH3F polar or non polar?
This compound, called propane, is nonpolar.
How do you know if a molecular compound has a dipole-dipole attraction?
A dipole moment is defined as a measure of the molecular polarity of a compound; the magnitude of the partial charges on the ends of a molecule times the distance between them (in meters). In order for there to be a dipole moment the element must must have molecular polarity which results from molecules with a net imbalance of charge (often a result of differences in electronegativity). If the molecule has more than two atoms, both shape and bond polarity determines the molecular polarity. In general look for a difference in electronegativity of the elements of a molecule which results in polarity and thus a possible dipole moment. Note that molecular shape influence polarity so molecules with the same elements but a different shape (and vice versa) won't have the same dipole moment.
What is the polarity of IO3?
What is the electronegativity and hardness of SO3
What is molecular dipole moment?
The molecular dipole moment is a measure of the separation of positive and negative charges within a molecule. It is a vector quantity that indicates the overall polarity of a molecule. It is determined by the individual dipole moments of the bonds within the molecule and their spatial arrangement.
Does H2 have a molecular dipole moments?
No. H2 does not have a permanent dipole moment.
Is a dipole polar or nonpolar?
Nonpolar compounds do not have dipole moments. Dipole moments are polar forces. If the compound is nonpolar then there is no polarity within that molecule.
What molecule possesses a net dipole moment?
Typically one where bond dipoles do not cancel due to the molecular symmetry. The lone pairs also give rise to a small dipole moment and these may cancel out small bond dipoles it depends on the relative directions of the dipole moments.
When do dipole dipole forces occur?
when there is a high difference in electronegativitity and a polar bond forms
Boron trichloride is gas but Nitrogen trichloride is liquid Why?
because of molecular dipole moments
What determines whether a molcule has an overall dipole moment?
Generally if a molecule contains polar bonds and the bond dipole moments do not cancel each other out then that molecule will have an overall dipole moment. Bond dipoles arise when there is a significant difference in electronegativity between the atoms in the bond. There some cases such as phosphine PH3 where the lone pair can make a significant contribution to the molecular dipole moment.
How might a molecule with two strong bond dipoles have no molecular dipole at all?
A molecule with two strong bond dipoles can have no molecular dipole if the bond dipoles cancel each other out by pointing in exactly opposite directions. For example, in carbon dioxide (a linear molecule), the carbon-oxygen bonds have a large dipole moment. However, because one dipole points to the left and the other points to the right, the dipoles cancel and overall there is no molecular dipole.
Describe a molecular dipole?
molecule or part of a molecule that contains both positively and negatively charged regions
Mathematically why do the dipole moments cancel in a carbon tetrachloride molecule?
Carbon tetrachloride is tetrahedron shaped, it is 100% symmetrical. Thus all the 4 bond dipole moments cancel each other and the net dipole moment is zero.

What is the molecular dipole moment?
a separation of charge forming a positive and negat2ive end of molecule
