4.Chemical Bonding and Molecular Structure
easy
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
A
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
(AIIMS-1980)
Solution
As can be seen from the formula of Bond Order, it can assume value-positive, integral or fractional, including zero.
$B.O. =\frac{\text { number of bonding electrons }-\text { number of antibonding electrons }}{2}$
