Discussion
Which one of the following molecules has the lowest bond length (in pm)?
Answer: C
The shortest bond is in HF.
Bond length depends mainly on the sizes of the bonded atoms. Hydrogen is the smallest atom, so the H-F bond is very short, about 92 pm.
The others are longer: O2 about 121 pm (a double bond, but between two larger atoms), F2 about 142 pm, Cl2 about 199 pm and Br2 about 228 pm, increasing as the halogen atoms get larger down the group.
