MCQ
Boiling point of acetone is ........ $^oC$
  • $56$
  • B
    $60$
  • C
    $100$
  • D
    $90$

Answer

Correct option: A.
$56$
a
At atmospheric pressure acetone has a boiling point of $56^{\circ} C$.being polar molecule, so there is dipole-dipole interactions between neighboring acetone molecules in the liquid phase. However, they are not as strong as the hydrogen bonds between water molecules. Therefore, less energy is required to vaporize acetone.
