Antiperiplanar definition chemistry
An elimination reaction is a type of organic reaction in which two substituents are removed from a molecule in either a one or twostep mechanism. The onestep mechanism is known as the E2 reaction, and the twostep mechanism is known as the E1 reaction.(chemistry) Describing a torsion angle between 150 and 180 Antiperiplanar dictionary definition antiperiplanar defined antiperiplanar definition: Adjective (not comparable) 1. antiperiplanar definition chemistry
In 1b, the dihedral angle between the leaving group and the highlighted beta hydrogen is 180, and the alpha carbonleaving group bond and the beta carbonhighlighted hydrogen bond are parallel to each other. In conformation 1, the leaving group and the highlighted beta hydrogen are said to be antiperiplanar, antiparallel, or anticoplanar.
Antiperiplanar definition chemistry free
AntiPeriplanar Definition Antiperiplanar refers to a periplanar conformation where the dihedral angle between two atoms or groups of atoms is between 150 and 180. In texts, antiperiplanar means bonds are anticoplanar.

E2 Stereochemistry E2 reactions occur most rapidly when the H C bond and C LG bonds involved are coplanar, most often at 180 o with respect to each other. This is
a torsion angle between 150 and 180 is called antiperiplanar (ap), also called antior transconformation; Torsional strain results from resistance to twisting about a bond. Special cases. In npentane, the terminal methyl groups experience additional pentane interference.

Illustrated Glossary of Organic Chemistry Periplanar: Atoms, groups, bonds having a torsional angle between 0 o and 30 o ( synperiplanar ) or between 150 o and 180 o ( antiperiplanar ).
The top conformation is known as synperiplanar and the bottom is known as antiperiplanar.
