Question

Which of the following alkanes cannot be prepared using Wurtz reaction?
[0.77 Mark]

• A. $C_2{H}_6$
• B. $C_4{H}_{10}$
• C. $C_6{H}_{14}$
• D. $C{H}_4$

Answer 1

The correct option is D $C{H}_4$

Wurtz reaction is used to prepare higher alkanes.
$RX+RX+2Na\stackrel{\text{Dry ether}}{\to }R-R+2NaX$
So $C{H}_4$ is not prepared using Wurtz Reaction.
