2015-10-22 · Anti addition dominates due to the cyclic bromonium ion transition state. Summary - Syn vs Anti Addition Alkenes are characterized by the addition reactions, which are categorized into two types based on the stereochemistry;syn addition and anti addition. During the addition, p bond of C=C breaks to form new σ bond. In syn addition, both nucleophile and electrophile In this example, it is impossible to tell from the product whether the mechanism was syn- or anti-addition. Let's look at the two possible products. After anti- or syn-addition of bromine, two compounds are produced that look different. However, facile bond rotation around the C1-C2 bond shows that they are in fact the same compound.

In anti addition, two substituents are added to opposite sides (or faces) of a double bond or triple bond, once again resulting in a decrease in bond order but an increase in number of substituents. The classical example of this is bromination (any halogenation) of alkenes. Aldol synthesis gives rise to stereocenters in the molecule.

Syn and anti addition is similar to these topics: Alkene, Unsaturated hydrocarbon, Nucleophilic addition and more.

Strong acid protonates the alkene, generating free carbocation. Watch out for possibility of rearrangements when a tertiary carbocation could be generated through 10.8.1. Anti-Markovnikov addition of HBr to alkenes We saw in section 10.4 that under normal conditions, HBr adds to an unsymmetrical alkene to form an alkyl halide where the H goes onto the less substituted carbon, and the Br goes onto the more substituted carbon – thus, it obeys Markovnikov’s Rule. However, when heated in the presence of a dialkyl peroxide (often written as ROOR), a Halogenation of alkene using B r 2 / C C l 4 is syn addition but not anti addition. If this is true enter 1, else enter 0.
