NEET2012ChemistryChemical Bonding and Molecular StructureActual
The pair of species with the same bond order is
Options
- AO ₂²⁻, B ₂
- BO ₂⁺, NO ⁺
- CNO , CO
- DN ₂, O ₂
Correct answer
A. O ₂²⁻, B ₂
Step-by-step solution
Bond order of ( O ₂ ²⁻ ) : Electronic : ( 1 ~s ^2 ^ ( s ^2 2 ~s ^2 ^* 2 ~s ^2 2 P _ z ^2 ( 2 P _ x ^2= 2 P _ y ^2 ) . ) ( ( 2 P _ x ^2= 2^ P _ y ^2 ) ^ 2 pz ^ ) Bond order (= Bonding - Antibonding electrons 2 = 10-8 2 =1 ) Bond order of (B₂ ) : ( 1 s^2 _ 1 s ^2 2 _ 2 s 2 ^ 2 s^2 2 p_z^2 ) Bond order (= 6-4 2 =1 ) ( O ₂ ²⁻ ) and ( B ₂ ) has same bond order 1.
