Which of the below molecules has no net dipole moment?
For the following molecules, use the dipole moment symbol to show the direction of the molecular dipole moment in all molecules that have an overall molecular dipole. Note for this one you do NOT need to draw the individual bond dipole moments, just the overall molecular dipole moment,
Based on the electronegativities of C, H, and Cl, would you expect the Cl3CCCH molecule to be polar or nonpolar? A molecule is polar if the vector sum of its bond dipole moments is not equal to zero. A molecule is nonpolar if the vector sum of its bond dipole moments is equal to zero. Pauling electronegativity values are listed in the periodic table on the last page of this handout.
A. Polar molecule
B. Nonpolar molecule
Which pair of elements listed below would be expected to form an ionic bond rather than a covalent bond?
A. C–Mg B. C–Li C. Al–Cl D. H–F E. O–Na
F. More than one pair, but not all of them, would form ionic bonds rather than covalent bonds.
G. All of these pairs would form ionic bonds.
H. None of these pairs would form ionic bonds.
Circle the molecule with the smallest dipole moment.
