2. Why is the soap derived from coconut oil so soluble?

Identify which among the two drugs is more water soluble and why? QH HO CH3 CH3 CH3 ČH3 DRUG #2 DRUG #1

1. If you get oil on your hands, and try to wash them with just water, it won’t remove the oil. Why? 2. If you add soap to your hands, you can now wash away the oil. This is because soap can interact with both oil and water. Based on this information, what term would you use to describe soap?
