The correct order of increasing s character ( in percentage ) in the hybrid orbitals in below molecules `//` ions is ( assume all hybrid orbitals are exactly equivalent) `:`
`underset(I)(CO_(3)^(2-))" "underset(II)(XeF_(4))" "underset(III)(I_(3)^(-))" "underset(IV)(NCl_(3))" "underset(V)(BeCl_(2)(g))`

Options

A. `II lt III lt IV lt I lt V`
B. `II lt IV lt III lt V lt I`
C. `III lt II lt I lt V lt IV`
D. `II lt IV lt III lt I lt V`

Answer

A

Explanation

`|{:("Species","Hydridisation"),(CO_(3)^(2ɵ),sp^(2)),(XeF_(4),sp^(3)d^(2)),(l_(3)^(ɵ),sp^(3)d),(NCl_(3),sp^(3)),(BeCl_(2),sp):}|`
