2). Because conc. H2So4 acts as a dehydration agent and dehydrates ethanol to ethene and when a molecule of H2 is added to it it becomes ethane
The process is electrolysis of water by electricity to create hydrogen (which can partly be used directly in fuel cells) and the addition of carbon dioxide CO2 (Sabatier process) to create methane.❤️
conc H2SO4 is a dehydrating agent which withdraw the water from ethanol and make ethane
CH3CH2OH + conc H2SO4 ⇒ CH3CH3 + H2O
conc. h2so4 act as dehydrating agent(removes water molecule from ethanol) and also act as a catalyst in the reaction of converting ethanol to ethane.
conc. H2SO4 acts as dehydrating agent in the reaction of formation of ethene from ethanol. Conc. h2so4 act as dehydrating agent(removes water molecule from ethanol) and also act as a catalyst in the reaction of converting ethanol to ethane.
Conc.H2SO4 acts as a catalyst in the reaction
Ethanol can be converted to ethene in presence of concentrated sulphuric acid used as a dehydrating agent. It is called as dehydration reaction. b) Ethene can be converted to ethane by addition of hydrogen molecule. It is known as hydrogenation reaction.
Methane is a chemical compound with the chemical formula CH₄. It is a group-14 hydride and the simplest alkane, and is the main constituent of natural gas. The relative abundance of methane on Earth makes it an attractive fuel, although capturing and storing it poses challenges due to its gaseous state under normal conditions for temperature and pressure
The Sabatier reaction or Sabatier process was discovered by the French chemist Paul Sabatier and Jean-Baptiste Senderens in 1897. It involves the reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures in the presence of a nickel catalyst to produce methane and water
