STANDARD Chemistry Isostructural Species MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Isostructural species are those which have the same shape and hybridisation. Among the given species, identify the isostructural pairs.
A
[NF₃ and BF₃]
B
[BF₄⁻ and NH₄⁺]
C
[BCl₃ and BrCl₃]
D
[NH₃ and NO₃⁻]
Correct Answer
Option B
Detailed Explanation
NF₃ (pyramidal) and BF₃ (trigonal planar) are not isostructural. BF₄⁻ (tetrahedral) and NH₄⁺ (tetrahedral) are isostructural. BCl₃ (trigonal planar) and BrCl₃ (trigonal bipyramidal) are not isostructural. NH₃ (pyramidal) and NO₃⁻ (trigonal planar) are not isostructural. Thus, BF₄⁻ and NH₄⁺ are isostructural species.
