Question

Mark the incorrect statement in the following
[1994]
(a) The bond order in the species 0,, 0, and
0, decreases as oz > 02 > 02
(b) The bond energy in a diatomic molecule
always increases when an electron is lost
(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.​

Answer 1

Answer:

AThe bond order in the species $O_2 ,O_2^+ $ and $ O_2^-$ decreases as $O_2^+ > O_2 > O_2^-$

BThe bond energy in a diatomic molecule always increases when an electron is lost

CElectrons in antibonding MO contribute to repulsion between two atoms

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

Explanation:
