Question:

Explain why the anti-periplanar confirmation of dichloroethane is the lowest energy confirmation possible for the molecule.

Rahul R.
Answer:

This is because in this arrangement, the largest atoms (chlorine) are positioned as far away as possible from each other in a staggered arrangement, minimizing steric interaction between the two and lowering overall energy of the molecule.
