Official previous-year question

Held on 27 Jan 2024 · Verified 6 Jul 2026.

Options

A
${[\mathrm{Co}{({\mathrm{NH}}_{3})}_{6}]}^{3+}$
B
${\mathrm{BrF}}_{5}$
C
${[\mathrm{Pt}(\mathrm{Cl}{)}_{4}]}^{2-}$
D
${\mathrm{SF}}_{6}$

Solution

${[\mathrm{Co}{({\mathrm{NH}}_{3})}_{6}]}^{+3}-{d}^{2}{\mathrm{sp}}^{3}$ hybridization

In ${[\mathrm{Co}{({\mathrm{NH}}_{3})}_{6}]}^{3+}$ , $\mathrm{Co}$ is in $+3$ oxidation state with the configuration $3{d}^{6}$ . In the presence of ${\mathrm{NH}}_{3}$ a strong ligand, the $3d$ electrons pair up leaving two d-orbitals empty. Hence, the hybridization is ${d}^{2}{\mathrm{sp}}^{3}$ forming an inner orbital octahedral complex.

${\mathrm{BrF}}_{5}-{\mathrm{sp}}^{3}{d}^{2}$ hybridization

${[{\mathrm{PtCl}}_{4}]}^{-2}-{\mathrm{dsp}}^{2}$ hybridization

${\mathrm{SF}}_{6}-{\mathrm{sp}}^{3}{d}^{2}$ hybridization
