Propanone is miscible in water due to:
Correct answer: D. All of these
- A. Both are polar molecules
- B. Hydrogen bonding between them
- C. Dipole-dipole attraction between them
- D. All of these
Explanation
Propanone (also known as acetone) is a polar molecule due to the presence of a carbonyl group. Water is also a polar molecule due to its bent molecular geometry and electronegativity difference between hydrogen and oxygen atoms. Both propanone and water are capable of forming hydrogen bonds. Propanone can donate and accept hydrogen bonds through its carbonyl oxygen, and water can form hydrogen bonds due to its hydrogen atoms. Dipole-dipole attractions occur between polar molecules. Since both propanone and water are polar molecules, they can experience dipole-dipole attractions.

About Hydrogen Bonding
Hydrogen bonding is the strong attraction between hydrogen attached to nitrogen, oxygen or fluorine and an electronegative atom in the same or another molecule. It explains unusual boiling points, viscosity, surface tension, water's properties and the difference between intermolecular and intramolecular hydrogen bonding.
