MCQ
Bond order is a concept in the molecular orbital theory. It depends on the number of electrons in the bonding and antibonding orbitals. Which of the following statements is true about it ? The bond order
  • ✓
    Can assume any positive or integral or fractional value including zero
  • B
    Has always an integral value
  • C
    Can have a negative quantity
  • D
    Is a non zero quantity
✓

Answer

Correct option: A.
Can assume any positive or integral or fractional value including zero
a
As can be seen from the formula of Bond Order, it can assume value-positive, integral or fractional, including zero.

$B.O. =\frac{\text { number of bonding electrons }-\text { number of antibonding electrons }}{2}$
