Question
Calculate the fractional bond order for the $S-O$ bonds in the sulphate ion ($SO_4^{2-}$).
Answer: C
💡 Solution & Explanation
The sulphate ion has 6 total bonding electron pairs (two double bonds, two single bonds in its Lewis structure) resonating symmetrically over 4 oxygen atoms. Bond Order = $6 / 4 = 1.50$.
