1. In the hydration of ethene to produce ethanol, why is a high pressure a problem?

  • It leads to the unwanted polymerisation of ethene to poly(ethane)
  • It leads to the unwanted polymerisation of ethene to poly(ethene)
  • It leads to the unwanted polymerisation of ethene to poly(propene)
  • It makes the reaction too endothermic
