Among the triatomic molecules/ions, BeC l _ 2 , N _ 3 ^ - , N _ 2...

${BeCl}_{2} , {{N}_{3}}^{-}, {N}_{2}O, {{NO}_{2}}^{+}$ is the linear molecule where the hybridization of the central atom does not have contribution from the $d -$orbital.

In the remaining molecules/ions,${O}_{3}$ is bent, ${SCl}_{2}$ is V shaped with ${sp}^{3}$hybridization,${{ICl}_{2}}^{-}, {{I}_{3}}^{-}$ and ${XeF}_{2}$, are linear with ${sp}^{3}d$ hybridization.
