Question

Alkyl halides are used for the preparation of which of the following?

• A. Alkane
• B. Alkene
• C. Alcohol
• D. All of these

Hint:

Remember: SN1/SN2 (→ alcohol), E1/E2 (→ alkene), and coupling (→ alkane) are the three classic pathways for R–X.

Answer 1

The Correct Option is D

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.
