1.) Structures & preparation for anionic, cationic, nonionic, amphoteric surfactant 2.) What is Co-surfactant and its working principle Please conclude a general method for preparation of each type, but not one by one, for example, the anionic one, please provide one or two methods, but not one method for soap, alkylbenzene sulfonates, alkyl sulfates, alkyl ether sulfates. Thank you.
2. Identify if each monomer would be best for cationic or anionic polymerization, or if it could be used for both. Explain your reasoning with words or pictures. OCH3

4. Why is an anionic surfactant more stable at alkaline condition and a cationic surfactant more stable at acid condition? 5. An emulsion of oil in water is more stable towards creaming if the oil particles have small sizes. What is your explaination?
4. Isobutylene undergoes cationic polymerization in the presence of strong Lewis acids like AICI, but it is not polymerized by free radicals or anionic initiators. Acrylonitrile, on the other hand, is polymerized commercially by free radical means also by anionic initiators like potassium amide but does not respond to cationic initiators. Explain this difference in behavior of isobutylene and acrylonitrile in terms of monomer structure and what intermediates would be formed under each polymerization condition CN Acrylonitrile Isobutylene

"How does a positive, neutral (zwitter) and negative amino acid effect a cationic surfactant?" Can someone please explain in details using Arginine, Isoleucine and Glutamic acid as explain? Also, how each can effect the Critical Micelle Concentration of a cationic surfactant? This is for my PCHEM lab btw.
Thanks!
6. Consider iron (II) chloride, FeCl2. (a) What is the ratio of the cationic to the anionic radius? (b) Based on this ratio, what type of coordination geometry does it form? (c) What is the coordination number? (d) Is FeCl isomorphous with SiO2, which has a tetrahedral coordination geometry? Why or why not? (4 marks) 7. Based on their chemical formulas, what is the structure (e.g. sheet silicate) for the following minerals? a) liberite, LizBeSiO4; (b) jadeite, NaAlSi206? (2...
