Which is more stable NI3 NF3 NBr3 NCl3?

All the trihalides of nitrogen are stable except NCl3, NBr3 and NI3. The unstable nature of NCl3, NBr3 and NI3 is due to low polarity of NX bond and a large difference in the size of nitrogen and halogen atom. Hence, NH3 will be stable.

Which is more stable NF3 or NI3?

NF3 is stable but NCl3 and NI3 are readily hydrolysed and are explosives.

Why NF3 is very stable and inert in nature?

Nitrogen has very small size as compared to the halogens, which have much larger sizes. Due to this, they can not remain bonded to the nitrogen atom and hence are highly unstable. As of NF3, it is stable and highly inert gas at room temperature.

Why is NH3 more stable than NF3?

NF3 is stable as the sizes of fluorine and nitrogen are comparable and the bonding interaction is good enough to give a stable compound. Also since chlorine atoms are larger than fluorine, the lone pair-lone pair and lone-pair bond-pair repulsion are also larger rendering nitrogen trichloride even more unstable.

Why NF3 is stable while other trihalides are unstable?

NF3 is stable. Hint:Nitrogen is smaller in size. For this reason, it can accommodate only atoms that are smaller in size. trihalides are always unstable due to its large size of the halogen atom.

Why are trihalides of nitrogen least stable?

Trihalides of nitrogen are least stable because N-X bond is weak. Weakness of N-X bond is because of large deference in the size of nitrogen and halogen atom.

Why are Trihalides of nitrogen least stable?

Which is the most stable Trihalides of nitrogen?

NF3
NF3 is the only halide of nitrogen that is stable.

Why NF3 is less polar than NH3?

As F is right of N in the periodic table so the electronegativity of F is greater than the electronegativity of N. So each of N – F bonds has its polarity towards F, which results in a net polarity which opposes the polarity of lone pair electrons. That’s why the dipole moment of $N{F_3}$ less than that of $N{H_3}$.

Which is stronger NF3 or NH3?

NH3 is more basic than NF3. In NF3,N is less electronegative than F, hence bond pair shifts more towards F, thereby δ positive charge density on N increases, hence tendency to donate electron decreases. Hence NH3 is more basic as compared to NF3.
