WebA σ bond allows free rotation around the bond a π. This preview shows page 18 - 20 out of 20 pages. • A σ bond allows free rotation around the bond. • A π bond restricts rotation around the bond because porbitals must be parallel to each other to overlap most effectively. The π bond is broken during rotation around the bond. WebBond rotation: Rotation around the line between two bonded atoms (the bond axis), where one end of the bond is stationary and the other rotates. Syn - eclipsed conformation. Anti - staggered conformation. C2 …
