Answer the following questions for the preparation of soap laboratory
Homework Answers
3. Detergents are generally ammonium or sulphonate salts of long chain carboxylic acids and consists of a hydrophobic tail and hydrophilic head. The hydrophobic tail is made up of long chain hydrocarbons which attracts oily substances like grease while the hydrophilic head i.e. carboxylate group attracts the water. Longer the hydrocarbon chain attracts the oily substances more so sodium methyl sulfonate contains shortest hydrocarbon so it does not effectively binds with the oily substances and thus considered as poor detergent.
4. Soaps are sodium or potassium salts of long chain carboxylic acids and are made by saponification of fat or vegetable oils by using sodium or potassium hydroxide.

In Organic Chemistry II for the 'Preparation and Properties of Soap' lab, please help answer the following questions; 1. Write out a step-by-step mechanism for saponification. You may begin with a simple ester such as ethyl acetate. 2. The experimental procedure directs you to generously lubricate (grease) the ground glass connection between the 10 ml r.b flask in which saponification is being carried out and the reflux condenser. Why is this generous lubrication needed?
