bond length

Postby leediane0916 » Tue Oct 30, 2018 7:43 pm

when we draw our lewis structures, does dr lavelle want us to indicate that triple double single bonds have different bond lengths or can they all just be the same length?

The lewis structures are just quick drawings of the shape of the molecule. You would not have to get detailed enough to show different bond lengths. The overall goal is to just show the relationship between the different atoms.

I think he cares more about us knowing what each bond represents and the possible resonance for each molecule than drawing the bond lengths correctly. Also, the bond length differences for triple/double/single/etc. bonds are relatively small and would be extremely difficult to draw accurately on a test or exam.
