I think so. I believe that if an atom has more lone pairs it will have a longer and weaker bond with surrounding molecules that also have lone pairs. Since electrons repel each other, the lone pairs would want to be as far away as possible from other lone pairs on bonded atoms. In class, Dr. Lavelle commented that F2 would have a larger than expected bond length because the lone pairs on each Flourine atom would repel each other. I'm not sure about if the other atoms don't have lone pairs but I would think there would be a degree of repulsion between lone pairs and bonded electron pairs.
I think lone pairs affect bond lengths because lone pairs cause repulsion. Structures without lone pairs have no extra repulsion except from the atoms in the molecule. Minimal e- repulsion causes the max distance between atoms.
