Question

Among the triatomic molecules/ions, $\mathrm{BeCl}_{2}, \mathrm{~N}_{3}^{-}, \mathrm{N}_{2} \mathrm{O}$, $\mathrm{NO}_{2}^{+}, \mathrm{O}_{3}, \mathrm{SCl}_{2}, \mathrm{ICl}_{2}^{-}, \mathrm{I}_{3}^{-}$and $\mathrm{XeF}_{2}$, the total number of linear molecule(s)/ion(s) where the hybridization of the central atom does not have contribution from the $d$-orbital(s) is\[Atomic number : $\mathrm{S}=16, \mathrm{Cl}=17, \mathrm{I}=53$ and $\mathrm{Xe}=54$ ]\

Professor PC Thomas Classes · Answer

(b) :  Thus, there are total four linear molecules/ions where the hybridisation of the central atom does not have contribution from the $d$-orbitals.
