Calculating Bond Lengths

[Tamera Scott 1G]

How do you calculate bond lengths? Do you add the given lengths with a fraction of the number of resonance structures?

[Alicia Gibbons 1B]

There are tables which give you the length of different bonds and differentiate between single, double, and triple bonds. When you have both a single and double bond, you would find the mean length. Same for other combinations.

[Catherine Kim 3K]

You calculate bond lengths by finding the mean/average of the given lengths. You also need to check if it is a resonance structure or not.

Weak (longer) bonds are easily broken and more likely involved in reaction.
Strong (shorter) bonds are harder to break and less reactive.

[Clarissa Cabil 1I]

You calculate bond lengths by finding the mean/average of the given lengths. You also need to check if it is a resonance structure or not.

In this case, if it has a resonance structure, what would you do?
