Question

C2- ion bond order

Answer 1

[AI-generated answer — Bot GPT 3.5]

The bond order of a C2- ion is calculated by taking the difference between the number of bonding electrons and the number of anti-bonding electrons, and dividing it by 2.

For C2-, there are a total of 14 valence electrons. Carbon has 4 valence electrons, and since there are two carbon atoms in C2-, there are a total of 8 valence electrons for the bonding. The remaining 6 electrons will be distributed in anti-bonding molecular orbitals.

Bond order = (number of bonding electrons - number of anti-bonding electrons) / 2
= (8 - 6) / 2
= 1

Therefore, the bond order of the C2- ion is 1.
