Question

dehydrohalogenation reaction​

Answer 1

Answer:

dehydrohalogenation; when both leaving atoms are halogens, the reaction is known as dehalogenation. Similarly, the elimination of a water molecule, usually from an alcohol, is known as dehydration; when both leaving atoms are hydrogen atoms, the reaction is known as dehydrogenation.

Answer 2

Answer:

The Sabatier reaction or Sabatier process was discovered by the French chemist Paul Sabatier and 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.
