Methane can’t be prepared by wurtz reaction

Web24 nov. 2024 · Methane cannot be prepared by either Wurtz reaction, Kolbe’s electrolytic method or by reduction of alkenes with H2. Where Wurtz reaction is not possible? Wurtz reaction generally fails when tertiary alkyl halides are used because tertiary alkyl halides include elimination reaction as side reactions. It happens due to steric – hindrance. 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 ...
