NEET2009ChemistryChemical Bonding and Molecular StructureActual
According to MO theory which of the following lists ranks the nitrogen species in terms of increasing bond order :
Options
- AN ₂⁻ < N ₂²⁻ < N ₂
- BN ₂⁻ < N ₂ < N ₂²⁻
- CN ₂²⁻ < N ₂⁻ < N ₂
- DN ₂ < N ₂²⁻ < N ₂⁻
Correct answer
C. N ₂²⁻ < N ₂⁻ < N ₂
Step-by-step solution
aligned & N ₂=14 e = B O =3 & ~N ₂⁻=15 e = B O =2.5 & ~N ₂²⁻=16 e = B O =2 aligned
