Question

sf₆ is...
a. a polar molecule with polar bonds.
b. a nonpolar molecule with polar bonds
c. a polar molecule with nonpolar bonds.
d. a nonpolar molecule with nonpolar bonds.

Explanation:

• Bond Polarity: The \(S - F\) bonds in \(SF_6\) are polar because of the difference in electronegativity between sulfur (\(S\)) and fluorine (\(F\)).
• Molecular Polarity: \(SF_6\) has an octahedral geometry. In an octahedral shape, the bond dipoles cancel each other out due to the symmetrical arrangement of the six \(S - F\) bonds. So, the overall molecule is non - polar.

Answer:

B. A nonpolar molecule with polar bonds
