Question

Identify the major product formed from the following:

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Wurtz reaction couples two alkyl halides using sodium metal in dry ether.

Answer 1

The Correct Option is D

Step (i): Converts alcohol to corresponding alkyl halide via Lucas reagent (HCl/ZnCl$_2$).
Step (ii): SN2 reaction — halide is replaced by iodide (Finkelstein reaction).
Step (iii): Wurtz reaction — two alkyl iodides in dry ether with sodium give higher alkanes. So, 1-butanol → 1-chlorobutane → 1-iodobutane → n-butane
