NEET2012ChemistryChemical Bonding and Molecular StructureActual
Which one of the following pairs is isostructural (i.e., having the same shape and hybridization)?
Options
- A[ BCl ₃ . and . BrCl ₃ ]
- B[ NH ₃ . and . NO ₃⁻ ]
- C[ NF ₃ . and . BF ₃ ]
- D[ BF ₄⁻ . and . NH ₄⁺ ]
Correct answer
D. [ BF ₄⁻ . and . NH ₄⁺ ]
Step-by-step solution
If number of bond pairs and lone pairs are same for the given pairs, they are isostructural. (a) (b) (c) (d) Thus, BF ₄⁻ and NH ₄⁺ are isostructural.
