Lengths of Single & Double Bonds

Postby Isabel_Eslabon_2G » Thu Nov 05, 2020 8:50 am

I don't remember if Lavelle spoke on this already, so I will just ask about it here.
If we are asked about lengths of single & double bonds on exams, do we need to memorize common ones (like C=C, or C-H) or will they be given in the question? Or do we get a reference chart for it?

I don't think we would ever have to memorize these, I think in lecture the professor said he looked them up as well. I wouldn't worry about it! If there is a question on it the lengths will be given. However, we may be asked to compare the lengths of bonds (a single vs a double, for example).

I don't think we need to memorize them, so I believe if we would need them to solve a problem, they'd be given in the question.

However, it's useful to know the general correlation that as the number of bonds increases, the length of the bonds decreases. For example, a double bond is shorter than a single bond, and so on.

I do not think we will have to memorize these values (just remember that single bond is longer than double bond)

So far, we do not need to memorize them yet. In the lecture, he said he had looked them up when he gave us the values, so I think we will either be given the lengths or later be told to memorize them.
