why we cant prepare methane by wurtz reaction - Brainly.in
WebWurtz reaction forms coupled products only. The Wurtz reaction is: 2R−X+2Na→R−R+2Na +X −. CH 4 contains only one carbon, so it cannot be formed by Wurtz reaction. So, option ( A ) is correct. Solve any question of Hydrocarbons with:-. Patterns of problems. WebThe Wurtz reaction between R-X and R'-X yields not only R-R' but also R-R and R'-R'. This mixture cannot be separated easily. * Methane cannot be prepared by this method. * A modification of this reaction involving alkyl and aryl halides is called Wurtz-Fittig reaction. If only aryl halides are subjected to coupling, the reaction is called as ...
