The Fluorine gauche Effect and a Comparison with Other Halogens in 2‐Halofluoroethanes and 2‐Haloethanols

While the gauche effect in 1,2‐difluoroethane is widely known as being due to hyperconjugative interactions between σCH electron‐donating orbitals and σ*CF electron‐accepting orbitals, the corresponding 1,2‐dichloro, 1,2‐dibromo, and 1,2‐diiodo derivatives are preferentially in the anti conformation...
