How do you figure our the bond lengths of a structure?

This depends on the electronegativity of the atoms creating the bond

Bond length is shortest for a triple bond, middle for a double bond, and longest for a single bond. For single bonds, the example HF,HCl,HBr,HI helps further explain bond length. As you move down the halogen family there are more electrons and a larger atomic radius causing more distance between the two atom centers. This would cause H-halogen bonds to increase in length down the family. As bond length increases, bond strength also decreases. I hope this helps.

i find bond lengths by doing lewis structures. single bonds are the longer, weaker bonds. double bonds are in the middle. triple bonds are the shorter, stronger bonds.

Triple are smaller than double, double smaller than single, however in reality because of resonance all of the bonds in the molecule will be about the same on average, just smaller the more multiply bonded it is.

single bonds are the longest and the weakest, triple bonds are the shortest and strongest
