MCQ
Among the following, which hydrocarbon is not produced by Wurtz reaction?
- ✓Methane.
- BEthane.
- CPropane.
- DAll given options can be prepared.

Answer
Correct option: A.
Methane.
By Wurtz reaction, higher alkanes are prepared.
i.e., $\text{R}-\text{Cl}+2\text{Na}+\text{R}-\text{Cl}\overrightarrow{\ \ \ \ \ }\ \text{R}-\text{R}+2\text{NaCl}\\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ _{\text{Alkane}}$
Thus, methane cannot be prepared by this reaction.
