  • What is the boiling point of anhydride?

    Boiling point
    Ethanoic anhydride boils at 140°C. This is because it is a fairly big polar molecule and so has both van der Waals dispersion forces and dipole-dipole attractions. It does not, however, form hydrogen bonds. That means that its boiling point isn't as high as a carboxylic acid of similar size.

  • What is the normal boiling point of acetic acid?

    118 °CPure acetic acid, often called glacial acetic acid, is a corrosive, colourless liquid (boiling point 117.9 °C [244.2 °F]; melting point 16.6 °C [61.9 °F]) that is completely miscible with water.

  • Why acetic anhydride has high boiling point than acetic acid?

    These have more surface area so have strong van der Waals Force of attractions. Hence they have higher boiling point.
  • It is used in the synthesis of Heroin by diacetylation of Morphine and thus also banned in many countries.
