WebWurtz reaction: RX+2Na+XR→R−R+2NaX. Kolbe's electrolysis: 2RCOOK+2H 2O→R−R+2CO 2+2KOH+H 2. Sabatier senderens reaction: C nH 2n+H 2→C nH 2n+2+heat. In kolbe process and Sabatier - senderens reaction R-R forms as a product so methane can not be formed by these methods. Solve any question of Hydrocarbons with: … Web13 Points. Because electrolysis takes place with minimum no of alkanoicacid salts therefore methane cannot be prepared. methane could not be prepared by Kolbe electrolysis method as there is formation of alkyl radicle and two alkyl radicle combine to form alkane .but in methane there is only one carbon so it is not prepared.
