Question
Assume that N2 absorbs a photon and an electron is raised to the first excited state.
The excited N2 is less stable than N2 in the ground state
The excited N2 is more stable than N2 in the ground state
The bond length of N2 in the excited state is shorter than the bond length of N2 in the ground state.
The excited state molecule will break up into two nitrogen atoms.
none of the above
a.The excited N2 is less stable than N2 in the ground state
b.The excited N2 is more stable than N2 in the ground state
c.The bond length of N2 in the excited state is shorter than the bond length of N2 in the ground state.
d.The excited state molecule will break up into two nitrogen atoms.
e.none of the above
Explanation / Answer
a.The excited N2 is less stable than N2 in the ground state (The excited electron will be in an antibonding orbital.)
