Calculation of Bond Order of Oxide based Acid Radials
NOTE: This formula is very very important for NEET, IIT-JEE, GATE, IIT-JAM, CSIR, SLET, DRDO, TIFR, ICT, IISc, and other entrance exams.
Examples:
SO4−2:
Valency of peripheral atom (i.e. oxygen) = 2
Charge on acid radical = −2
Number of peripheral atoms = 4
So, the Bond Order = 2 + (−2 ÷ 4) = 1.5
PO4−3:
Valency of peripheral atom (i.e. oxygen) = 2
Charge on acid radical = −3
Number of peripheral atoms = 4
So, the Bond Order = 2 + (−3 ÷ 4) = 1.25
MnO4−:
Valency of peripheral atom (i.e. oxygen) = 2
Charge on acid radical = −1
Number of peripheral atoms = 4
So, the Bond Order = 2 + (−1 ÷ 4) = 1.75
ClO4−:
Valency of peripheral atom (i.e. oxygen) = 2
Charge on acid radical = −1
Number of peripheral atoms = 4
So, the Bond Order = 2 + (−1 ÷ 4) = 1.75
