Why does sugar dissolve in water more easily than oil?a)Sugar molecule...
Sugar dissolves in water more easily than oil because sugar molecules are polar, meaning they have positive and negative charges that can interact with the polar water molecules. When sugar is added to water, the water molecules surround and bond with the sugar molecules, pulling them into solution. This process is known as dissolution. In contrast, oil molecules are non-polar and do not interact with water molecules, leading to oil floating on the water's surface rather than dissolving into it.

Why Sugar Dissolves in Water More Easily Than Oil
When we explore why sugar dissolves in water but oil does not, the key factor lies in the interaction between the molecules.
1. Molecular Interactions
- Sugar molecules are polar, meaning they have a positive and a negative end.
- Water is also a polar substance, allowing sugar molecules to form strong interactions with water molecules.
- These interactions happen through hydrogen bonding, where the positive end of the water molecule attracts the negative end of the sugar molecule, helping sugar dissolve.
2. Oil's Non-Polar Nature
- In contrast, oil molecules are non-polar. They lack the positive and negative charges that sugar and water possess.
- Non-polar molecules do not interact effectively with polar molecules like water.
- As a result, oil does not dissolve in water, leading to a separation between the two substances.
3. Summary of Key Points
- Sugar dissolves in water due to strong molecular interactions.
- Polar sugar molecules attract water molecules, facilitating dissolution.
- Non-polar oil cannot form these interactions and thus does not dissolve.
In conclusion, the ability of sugar to dissolve in water more easily than oil primarily stems from the polar nature of sugar and the interactions it can form with water molecules. This fundamental difference in molecular properties explains the contrasting behaviors of sugar and oil in water.
