Q.
Which one of the following has (have) octahedral geometry ?
(i) $SbCl^{-}_6$
(ii) $SnCl^{2-}_6$
(iii) $XeF_6$
(iv) $IO^{5-}_6$
UPSEEUPSEE 2017Chemical Bonding and Molecular Structure
Solution:
Except (iii) i.e. $XeF _{6}$, all other show octahedral geometry.
$XeF _{6}$ has $6 \sigma$ bonds and one lone pair of electrons, hence show distorted octahedral structure also known as pentagonal bipyramidal with one lone pair.
