Based on molecular orbital theory,the bond order of the H-H bond in the H₂⁺ ion is ________. A)0 B)1/2 C)1 D)3/2 E)2

Question

Quizplus · Accepted Answer

The H₂⁺ ion has a total of 10 valence electrons. Based on molecular orbital theory, these electrons fill the molecular orbitals in order of increasing energy. The molecular orbital diagram for this ion would look like: (anti-bonding) S1P*2 + S1S*2 + P0*4 + S1U1*2 + B0*0 + B1U1*0 + S1U1*2 (bonding) The bond order is given by the difference between the number of bonding and anti-bonding electrons divided by 2. In this case, there are a total of 4 bonding electrons and 2 anti-bonding electrons, giving a bond order of (4-2)/2 = 1/2. Therefore, the answer is B) 1/2.
