JEE MAIN - Chemistry (2022 - 24th June Evening Shift - No. 7)
PCl5 is well known, but NCl5 is not. because,
nitrogen is less reactive than phosphorus.
nitrogen doesn't have d-orbitals in its valence shell.
catenation tendency is weaker in nitrogen than phosphorus.
size of phosphorus is larger than nitrogen.
Explanation
$$\mathrm{PCl}_{5}$$ is well known but $$\mathrm{NCl}_{5}$$ is not because nitrogen does not have vacant d-orbitals in its valence shell.
So, nitrogen cannot expand its octet. On the other hand, phosphorus has vacant $$\mathrm{d}$$-orbitals in its valence shell which enables it to expand its octet.
