The conditions necessary for the extraction of a water molecule from two molecules of ethanol are

  • A less acid and lower temperature
  • B excess acid and a lower temperature
  • C excess acid and a higher temperature
  • D less acid and a higher temperature

The correct answer is A. less acid and lower temperature

- The formation of ethoxyethane ( a sweet smelling liquid) can be considered a dehydration reaction

- This is because the overall reaction is the loss of one molecule of water from two molecules of ethanol

- If the alkanol is in excess instead of the acid in excess, and the temperature is lower.
