Web5 nov 2024 · Anti-periplanar refers to a periplanar conformation where the dihedral angle between two atoms or groups of atoms is between ±150° and 180°. In texts, anti-periplanar means bonds are anti-coplanar. The image shows butane (C 4 H 10) in a syn-periplanar conformation where the two methyl groups (-CH 3) are lined up with a 180° angle.
