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

The C=O bond makes acetone miscible and the C-C-C chain makes it miscible with hexane. The C=O is polar with water, and the C-C-C is non polar with hexane (like dissolves like). However, Hexane is non-polar and water is polar, so hexane is immiscible in water.

Answer 2

Hmmm makes sense. Thank You very much! :-)

Answer 3

No problem, anytime!
