reactions of ethene

• reduction/ hydrogenation of alkenes:

  reagent: hydrogen

  conditions: 150 degrees celsius with a nickel catalyst
• reduction: reacts an alkene with hydrogen and forms an alkane
• reduction produces one product and therefore has a 100% atom economy
• direct hydration of ethene forms an alcohol
• direct hydration of ethene produces one product and therefore has a 100% atom economy
• conditions for direct hydration of ethene:

  catalyst- concentrated phosphoric acid

  pressure- 6000kPa

  temperature- 300 degrees celsius
