mechanism predicts that 4b should be formed. may be nepiu to 61 Several natural products have been isolated from the flowering plant Sarcostemme acidum, which has been used in folk medicine as a cough suppressant During efforts to make these compounds in the laboratory, it was discovered that one of the natural products is readily converted into another one of the natural products in a cyclization reaction that occurs upon treatment with a strong acid.10 A similar cyclization is shown...

МСРВА Alkenes are oxidized to give epoxides on treatment with a peroxyacid, RCo,H, such as metachloroperoxybenzoic acid (MCPBA). Peroxyacids transfer an oxygen atom to the alkene with syn stereochemistry, i.e. both C-O bonds form on the same face of the double bond, through a single step mechanism without intermediates. The oxygen atom farthest from the carbonyl group is the one transferred. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions - XT...

In the case of conjugated dienes, that is dienes that are separated by one sigma bond, the carbocation that is formed is stabilized additionally by resonance. Addition of the nucleophile to the carbocation intermediate can therefore...

The sec-butyl cation can react as both a Lewis acid and a Brønsted- Lowry acid in the presence of a water-sulfuric acid mixture. In each case, however, the product is different. The two reactions are: 2. H2o +H3O+ a. In which reaction does this cation react as a Lewis acid? In which does it react as a Brønsted-Lowry acid? b. Write Lewis structures for reactants and products and show by...

1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
