Question

2. Nitrogen forms only NCI, but phosphorous forms PCI, and PCI, both. Explain.

​

Answer 1

Answer:

There is no vacant d-orbital in the outermost orbit of Nitrogen. ... There are valent d-orbitals in the outer most orbit of phosphorus and hence it shows variable covalence 3 and 5 in ground state and excited state respectively. Hence nitrogen forms only NCl3 but phosphorus forms PCl3 and PCl5 both

Explanation:

Like if got help from this..mark me as brainlist

Answer 2

P has the d orbital

so,

P forms PCl3,PI3,PBr3

thus,

N have no d orbital

so,

N froms only NCl3
