Question

Bond order depends on the number of bonding and anti-bonding orbitals. The bond order can never have:

• A. A negative value
• B. An integral value
• C. Assume any positive, or an integral, or a fractional value including zero
• D. a non zero value

Answer 1

The correct option is A A negative value

We know,
Bond order = $\frac{1}{2}$ (number of bonding electron(s) - number of anti-bonding electron(s))

Since the number of anti-bonding electrons can never be greater than the number of bonding electrons, the bond order can never be negative.
