Bond Length

Postby Nicole Garrido 2I » Sun Nov 11, 2018 7:11 pm

Is there a way to determine bond length or will it always be given?

I think it would be given, but in general you should just know conceptually that single bonds are the longest (and weakest), and then double bonds are shorter, and triple bonds are the shortest (and the strongest).

Bond length is the average of all the bonds added up in the molecule. So you would be given the different bond lengths, then you would add them up and divide them by the number of bonds.

I don't believe you will be expected to know specific bond lengths but you will need to know relative bond lengths. So you will need to know that single bonds are longer than double bonds and double bonds are longer than triple bonds. You will also need to know that atomic and ionic radii as well as lone pairs play a role in bond length.
