Question

If $N_{x}$ is the number of electrons in bonding molecular orbitals of an atom and $N_{y}$ is the number of electrons in antibonding molecular orbitals, then the molecule/atom will be stable if

• A. $N_{x} < N_{y}$
• B. $N_{x}=N_{y}$
• C. $N_{x}>N_{y}$
• D. $N_{x}\leq N_{y}$

Answer 1

Answer: (C)

Stability of $molecule/ions$ depends on number of electrons in bonding and antibonding molecular orbitals.

Electrons in bonding molecular $orbitals>electrons$ in antibonding molecular orbitals
