Bond Length

How do we determine bond lengths?

They are experimentally determined.

We don't determine bond lengths ourselves, we are given the lengths because they have been experimentally found from repeated experiments of different molecules involving the same atom.

Bond length is determined by the bond order, or the number of bonded electrons. This has to be derived from experiments.

As mentioned, it is determined experimentally. We just need to know that double bonds are stronger and shorter than single bonds.

The bond length is determined experimentally, so we do not determine the bond lengths ourselves.

The exact bond length is derived from experiments, but relative bond lengths can be determined from bond order.

You have to be given the actual bond length from previous experiments but there are general guidelines such as double bonds being shorter than single bonds.

single bonds are longest and weakest, triple bonds are shortest and strongest

bond lengths are determined experimentally. However, we can compare the bond lengths of different compounds through periodic trends and atomic radii.

We don't actually have to calculate bond length quantitatively. Just remember single bonds are longer than double and triple bonds
