Question

Acetone and water are miscible. Acetone and hexane are also miscible. What is the possible explanation for their miscibilities, considering that water and hexane are immiscible?

Answer 1

Acetone is miscible because it has a C=O bond, while its C-C-C carbon chain makes it miscible with hexane. However, hexane is non-polar while water is polar, and since the two molecules have different polarities, they are immiscible.
