In this lesson, we will learn how to describe the structure of anionic detergents and explain how they remove stains from fabrics.
Students will be able to
Detergents
Anionic detergent
Hydrophilic
Hydrophobic
Q1:
As well as removing stains, what other effect can anionic detergent molecules, such as those of alkylbenzene sulfonates, have when added to stained items in water?
Q2:
The structures of two alkylbenzene sulfonates are shown below.
Why might structure B be preferred over structure A as a commercial detergent?
Q3:
The following image shows a cartoon structure of sodium 4-dodecylbenzenesulfonate.
What structural arrangement will these molecules initially form when placed into water?
