What product is obtained when alkyl halides react with metallic sodium in presence of dry ether?
Options
- AAlkenes with same number of carbon atoms as in alkyl halide.
- BAlkynes with same number of carbon atoms as in alkyl halide.
- CAlkanes with same number of carbon atoms as in alkyl halide.
- DAlkanes with double the number of carbon atoms as in alkyl halide.
Correct answer
D. Alkanes with double the number of carbon atoms as in alkyl halide.
Step-by-step solution
Wurtz reaction: This involves coupling of two identical molecules of alkyl halide upon treatment with Na metal in presence of dry ether to give alkanes with double the number of carbon atoms as in alkyl halide as follows: R - X Na / dry ether R - R + NaX
