Question

Among $[I_3]^+$, $[SiO_4]^{4-}$, $SO_2Cl_2$, $XeF_2$, $SF_4$, $ClF_3$, $Ni(CO)_4$, $XeO_2F_2$, $[PtCl_4]^{2-}$, $XeF_4$, and $SOCl_2$, the total number of species having $sp^3$ hybridised central atom is ___.

SolveKar AI · Accepted Answer

Apply VSEPR + hybridization counts: $[I_3]^+$ — bent, $sp^3$ ✓. $[SiO_4]^{4-}$ — tetrahedral, $sp^3$ ✓. $SO_2Cl_2$ — tetrahedral around S, $sp^3$ ✓. $XeF_2$ — linear, $sp^3d$ ✗. $SF_4$ — see-saw, $sp^3d$ ✗. $ClF_3$ — T-shape, $sp^3d$ ✗. $Ni(CO)_4$ — tetrahedral, $sp^3$ ✓. $XeO_2F_2$ — see-saw, $sp^3d$ ✗. $[PtCl_4]^{2-}$ — square planar, $dsp^2$ ✗. $XeF_4$ — square planar, $sp^3d^2$ ✗. $SOCl_2$ — pyramidal, $sp^3$ ✓. Count: $5$ species are $sp^3$.
