Lengths of bonds

Why are double bonds shorter than single bonds?

Double bonds are shorter because they share more electrons, attracting the nuclei of two atoms closer together than a single bond does.

Double Bonds are shorter because they share more electrons between the two atoms, meaning that those two atoms are more tightly bonded are therefore closer together. The attraction between the two is greater than if it were just a single bond. Similarly, a triple bond would then have a shorter bond length than double and single bonds.

Bond Length: Single Bond > Double Bond > Triple Bond

Double bonds are stronger that single bonds. This means that double bonds have a stronger pull, resulting in a shorter length.
