Wurtz-Fittig reaction is used to prepare:
Select the correct option:
Solution
Incorrect! Answer:
Aryl-alkyl compounds
The Wurtz-Fittig Reaction is an extension of the Wurtz reaction, used to couple an aryl halide with an alkyl halide.
- General Reaction: Ar−X+R−X+2Nadry etherAr−R+2NaX
- Example: Treating Bromobenzene and Methyl bromide with Sodium gives Toluene (an aryl-alkyl compound).
- Compare:
- Wurtz Reaction: 2R−X+2Na→R−R (alkane)
- Fittig Reaction: 2Ar−X+2Na→Ar−Ar (biphenyl)
