Chemical Bonding And Molecular Structure Ques 84
84. In which of the following pairs, the two species are isostructural?
[2007]
(a) $SO_3{ }^{2-}$ and $NO_3{ }^{-}$
(b) $BF_3$ an $NF_3$
(c) $BrO_3{ }^{-}$and $XeO_3$
(d) $SF_4$ and $XeF_4$
Show Answer
Solution:
- (c) Hybridization of $Br$ in $BrO_3^{-}$
$H=\frac{1}{2}(7+0-0+1)=4$
hybridization $=s p^{3}$
Hybridization of $Xe$ in $XeO_3$.
$H=\frac{1}{2}(8+0-0+0)=4$
Hybridization $=s p^{3}$
In both cases, the structure is trigonal pyramidal.
