Question:
Alkyl halides are used for the preparation of which of the following?
Alkyl halides are used for the preparation of which of the following?
Show Hint
Remember: SN1/SN2 (→ alcohol), E1/E2 (→ alkene), and coupling (→ alkane) are the three classic pathways for R–X.
Updated On: Oct 14, 2025
- Alkane
- Alkene
- Alcohol
- All of these

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Known conversions of alkyl halides.
Alkyl halides are versatile: (i) Alkanes via Wurtz coupling (R–X + Na → R–R),
(ii) Alkenes via $\beta$-elimination (alc. KOH), and (iii) Alcohols via nucleophilic substitution (aq. KOH).
Step 2: Conclusion.
Since all three can be prepared from alkyl halides, the answer is (D) All of these.
