The most stable trihalide of nitrogen is.

Question

Canvas Classes · Accepted Answer

The stability of nitrogen trihalides depends on the N–X bond strength:

| Halide | N–X bond | Stability |
|---|---|---|
|  | N–F (strong, F is small) | Most stable |
|  | N–Cl (weaker) | Less stable |
|  | N–Br (even weaker) | Unstable |
|   | N–I (weakest) | Very unstable, explosive |

is the most stable because F is the smallest halogen and forms the strongest bond with N.
