Question

Wurtz reaction of methyl iodide yields an organic compound $X$. Which one of the following reactions also yields $X$?

• A. $C_2{H}_{5}Cl+Mg\stackrel{Dryether}{\to }$
• B. $C_2{H}_{5}Cl+LiAl{H}_4\to$
• C. $C_2{H}_{5}Cl+C_2{H}_{5}ONa\to$
• D. $CHC{l}_3\underset{\Delta }{\overset{Agpowder}{\to }}$

Answer 1

The correct option is B $C_2{H}_{5}Cl+LiAl{H}_4\to$

In the wurtz reaction , ethane is produced from methyl iodide as:
$2H_{3}C-I+2Na\stackrel{dryether}{\to }C{H}_3-C{H}_3+2NaI$ ; Therefore X = $C_2{H}_6$
X can also be prepared by the method (A) & (B) as:
$C_2{H}_{5}Cl+Mg\underset{H_{2}O}{\overset{dryether}{\to }}{C}_2{H}_6+Mg\left(OH\right)\left(Cl\right)$
$C_2{H}_{5}Cl+H_2\stackrel{LiAl{H}_4}{\to }{C}_2{H}_6+HCl$
