Which of the following have the highest boiling point: a) propanone b) ethanol c) water d) ethanoic acid

Question

Which of the following have the highest boiling point:

a) propanone

b) ethanol

c) water

d) ethanoic acid

Answer 1

Water will have the highest boiling point due to strong intermolecular hydrogen bonding. Ethanol and ethanoic acid also have strong hydrogen bonding but the number of hydrogen bonds in water is more. This is because there is two hydrogen atom attached to an electronegative atom or Oxygen atom.
