The mechanism followed by the reaction below is:CH3CH2Br → H2C=CH2 + HBr (Conditions: alcoholic KOH)
Correct answer: A. E2
- A. E2
- B. E1
- C. SN1
- D. SN2
Explanation
The formation of ethene shows that the reaction is elimination reaction Primary alkyl halides follow the E2 mechanism The alcohol medium shows elimination reaction.

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.
