Bond lengths
If not given the particular bond length between two molecules, is there a way to find out the bond length?

Re: Bond lengths
Not sure if you can, but when you do I believe it is the sum of the radii. Here's a link for the radii lengths of different atoms:

Re: Bond lengths
Bond lengths are accepted values that were experimentally obtained, so we would have to be given them as there is no equation to figure out a bond length
Re: Bond lengths
I believe that Dr. Lavelle mentioned this once in his lectures. A bond length between two molecules is about 10^-10m, which is equal to 1 Angstrom.

Yes, this is correct. A bond length is always equal to 1 angstrom

Yes! Multiple bonds will be shorter than single bonds.

Yes! Multiple bonds will be shorter than single bonds.
For example, because a double bond is stronger than a single bond, the double bond's length will be relatively shorter since the atoms are pulled together with more strength.

Re: Bond lengths
Bond lengths equal one Angstrom, and will lively be given. However, double bonds will be shorter than single bonds a lot of the time because they have a stronger pull between molecules, likely pulling them closer together and requiring a shorter bond.

Re: Bond lengths
Does anyone know that actual length of double and triple bonds? Will we need to know this on the tests?

Re: Bond lengths
There's no formula but there are very specific lengths for certain bonds that I doubt will be expected knowledge to know on the test
