Consider the reaction given below: Which statement is true?
Correct answer: D. Reaction II is elimination
- A. Reagent for I is KOH in alcohol
- B. Reagent for II is KOH in aqueous medium
- C. Reaction I is Debromination
- D. Reaction II is elimination
Explanation
Elimination of primary alkyl halides gives alkenes, reaction II is KOH in alcohol and reaction I is KOH in aqueous medium.

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.
