In which of the following would the bonding be strengthened with the addition of an electron to form the negative molecular ion? Question 16 options: a) N2 b) O2 c) F2 d) all of these e) none of these
Homework Answers
In each of the given diatomic molecules if we increase the number of electrons to form negative ion, the electron will go to antibonding molecular orbital which will decrease the BO
BO = (BMO electrons - ABMO electrons )/ 2
Hence it will decrease the strength in each of the molecules
So answer is: in none of these the bonding strength will increase
