Question
The BF3 molecule is nonpolar, whereas the NF3 molecule is polar. Which of the following statements accounts for the difference in polarity of the two molecules?
A.
In NF3, each F is joined to N with multiple bonds, whereas in BF3, each F is joined to B with single bonds.
B.
N − F bonds are polar, whereas B − F bonds are nonpolar.
C.
NF3 is an ionic compound, whereas BF3 is a molecular compound.
D.✓ Correct
Unlike BF3, NF3 has a nonplanar geometry due to an unshared pair of electrons on the N atom.
