Question

Which of the following nitrogen halides is most stable?

Options

• NI₃

• NBr₃

• NCl₃

• NF₃

Answer 1

NF₃

Explanation:

Among nitrogen halides, NF₃ is the most stable because the N-F bond is very strong due to the high electronegativity of fluorine and strong bond overlap. In contrast, heavier halides like NI₃, NBr₃, and NCl₃ have weaker bonds and are less stable, with NI₃ being especially unstable and explosive. Thus, stability increases with the decreasing size and increasing electronegativity of the halogen, making NF₃ the most stable nitrogen halide.
