Final answer:
Emulsifiers such as soap have amphipathic properties with a hydrophobic tail that interacts with non-polars like oil, and a hydrophilic head for polar substances like water.
Step-by-step explanation:
The correct answer is that the non-polar end of an emulsifier, which loves oil and hates water, is called hydrophobic. This term, which literally means "water fearing", refers to the tendency of non-polar substances to not mix with water.
These hydrophobic tails are often made up of long chains of hydrocarbons that are non-polar and repel water molecules, therefore mixing with fats or oils instead.
Emulsifiers, such as phospholipids in cell membranes or soap in cleaning agents, have a amphipathic nature, meaning they contain both a hydrophilic ("water-loving") and a hydrophobic region.
This duality allows them to interact with both water and oil, making it possible for the two to mix in the form of an emulsion. For example, soap molecules have a hydrophobic tail that dissolves in grease and a hydrophilic head that can interact with water, allowing grease to be washed away.
The correct answer is option hydrophobic. An example of a non-polar end of an emulsifier that loves oil and hates water is the hydrophobic tail of a soap molecule.
Soap acts as an emulsifying agent between grease and water because it contains both a polar and a nonpolar region. The nonpolar hydrocarbon tail of the soap dissolves into the oil, while the polar end interacts with water.
This allows the soap to stabilize an oil-water mixture, forming an emulsion that can be washed away.
