NEET2009ChemistryChemical Bonding and Molecular StructureActual
In which of the following molecules/ions BF ₃, NO ₂⁻, NH ₂⁻ and H ₂ O , the central atom is sp ^2 hybridised ?
Options
- ANO ₂⁻ and NH ₂⁻
- BNH ₂⁻ and H ₂ O
- CNO ₂⁻ and H ₂ O
- DBF ₃ and NO ₂⁻
Correct answer
D. BF ₃ and NO ₂⁻
Step-by-step solution
Key Idea For sp ^2 hybridisation, there must be either 3 bonds or 2 bonds and one lone pair of electrons in the molecule or ions. Thus, in BF ₃ and NO ₂⁻ , central atom is sp ^2 hybridised.
