Question

Oil mixes with water.

• A. True
• B. False

Answer 1

The correct option is B False

Immiscibility of Water

1. Oil is immiscible with water because it forms a separate layer on the surface of the water.
2. Oil and fats don't have any polar parts for them to dissolve in water to break some of the water hydrogen bonds.
3. Water due to presence of polar parts and absence of polar part in oils, water will not be able to dissolve oils hence oil are forced to dissolve in water.
4. Example: olive oil like every other hydrophobic substance is insoluble in water because the cohesive force between its molecules is greater than adhesive force, making its molecules stick together even when mixed in water, so they dissolve in organic solvents.

Therefore, due to no hydrophobic part in oils, they are immiscible in water, Hence the above statement is false.
