QAIPMT-2007-Ch-2289: NEET 2007 Chemistry - Class 11 AIPMT-2007-Ch-2289 Solution: In which of the following pairs, the two species are…

In which of the following pairs, the two species are isostructural?

Multiple Choice Options

A $SO_3^{2-}$ and $NO_3^-$
B $BF_3$ and $NF_3$
C $BrO_3^-$ and $XeO_3$
D $SF_4$ and $XeF_4$

Step-by-Step Verified Solution

Hybridisation of Br in BrO 3 � : = 1 2 ( 7 + 0 _ 0 + 1 ) = 4 Four hybrid orbital means sp 3 hybridisation. Hybridisation of Xe in XeO 3 : = 1 2 ( 8 + 0 _ 0 + 0 ) = 4 Four hybrid orbital means sp 3 hybridisation. Thus, both BrO 3 � and XeO 3 are sp 3 hybridised with three bond pairs of electrons and one lone pair of electrons and results in trigonal pyramidal shape.
