  • C
    $2 CH _{3} CH _{2} l+2 Na \rightarrow CH _{3} CH _{2} CH _{2} CH _{3}+2 Nal$
  • D
    $C H_{3} B r+A g F \rightarrow C H_{3} F+A g B r$

Answer

Correct option: A.
$C_{6} H_{5} l+2 N a+C H_{3} l \rightarrow C_{6} H_{5} C H_{3}+2 N a l$
a
The Wurtz-Fittig reaction is the reaction of an aryl halide with alkyl halide and sodium metal to give substituted aromatic compound.

Thus, Wurtz Fittig reaction is

$C_{6} H_{5} I+2 N a+C H_{3} I \rightarrow C_{6} H_{5} C H_{3}+2 N a I$
