WebAccording to understanding, the cyclic chloronium ion can be formed by elimination of both primary chlorine and secondary chlorine. So If AlCl3 eliminated secondary chlorine would the same product be formed? i.e. can either of the chlorine atom be eliminated to form the same product since they both have the same stability due to formation of cyclic … WebThe base peak is dominantly at m/z 91, 93 in each investigated case, although with the increasing chain length, its contribution to the total ion current exhibits some reduction. Among the possible fragmentation products, the five-membered chloronium containing ring is the most stable as measured by an isodesmic reaction, although the six-and ...

A halonium ion is formed by the addition of a halogenium ion X+ (where X+ is any halogen atom carrying a positive charge) to a C=C double bond, and often has a three-membered cyclic structure. Reaction of halonium ions with neutral molecules gives rise to various products. How Chloronium …

WebApr 5, 2013 · It would appear that the C-C π bond is acting both as a nucleophile (attacking Br) and an electrophile (accepting a pair of electrons from Br). Furthermore, the Br is acting both as electrophile (accepting a pair of electrons from the π bond) and nucleophile (donating a pair of electrons to the π bond). Only the role of the second Br is clear. girl at the doctorWebAlkenes react with chlorine in the presence of H0 to give a chlorohydrin via a cyclic chloronium ion intermec iate.
