Question

List the following bonds in order of increasing polarity.
A)N-O < N-N < N-F < H-F
B)N-N < N-O < N-F < H-F
C)H-F < N-F < N-O < N-N
D)N-N < N-O < H-F < N-F

To determine the polarity of bonds, we need to consider the electronegativity difference between the two bonded atoms. The greater the difference, the more polar the bond.

The electronegativity of nitrogen is 3.0, oxygen is 3.5, and fluorine is 4.0. Hydrogen has an electronegativity of 2.1.

Using this information, we can rank the bonds in order of increasing polarity:

N-N < N-O < N-F < H-F

Therefore, option B is the correct answer.
