In the reaction of ethene with bromine the intermediate formed is:
Correct answer: A. A
- A. A
- B. B
- C. C
- D. D
Explanation
The reaction of ethene with bromine is a typical example of electrophilic addition reaction. In this reaction, the first step involves the formation of an intermediate called a bromonium ion. This is formed due to the addition of bromine molecule across the double bond of ethene. The bromonium ion is a cyclic intermediate having a positive charge on the bromine atom. The correct representation of the intermediate formed in the reaction is given in (A) option. This intermediate is highly reactive and can react with a nucleophile to form the final product

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
