Based on molecular orbital theory, the bond order of the C-C bond in the C₂ molecule is __________. A)0 B)1 C)2 D)3 E)4

Question

Quizplus · Accepted Answer

According to molecular orbital theory, the bond order is calculated as (number of bonding electrons - number of anti-bonding electrons)/2. In the C₂ molecule, there are 8 bonding electrons (4 from each carbon atom) and 4 anti-bonding electrons (2 from each carbon atom). Therefore, the bond order is (8-4)/2 = 2, making choice C the correct answer.
