Mark the incorrect statement in the following :

A

The bond order in the species ` O_(2), O_(2)^(+) " and " O_(2)^(-)`
decreases as ` O_(2)^(+) gt O_(2) gt O_(2)^(-)`

B

The bond antibonding M.O. contribute to repulsion between two atoms

C

Electrons in antibonding M.O. contribute to repulsion between two atoms

D

With increase in bond order , bond length decreases and bond strength increases

Text Solution

Verified by Experts

The correct Answer is:
b
The removal of an electron from a diatomic molecule
may increase the bond order as in the conversion
` O_(2) (2) to O_(2)^(+) (2.5) ` or decreases the bond order as in
the conversion , ` N_(2) (3.0) to N_(2)^(+) (2.5)`. As a result , the
bond energy may increase or decrease . Thus
statement (b) is correct .
