and the effect that the solvent has on the rates of SN1 and SN2 reactions. The SN1 mechanism is a two-step nucleophilic substitution‚ or unimolecular displacement. In the first step of the mechanism‚ the carbon-halogen bond breaks and the halide ion leaving group leaves in a slow‚ rate-determining step to form a carbocation intermediate. The carbocation intermediate is then immediately detained by the weak nucleophile in a fast‚ second step to give the product. A solution of ethanol with some silver

therefore is less reactive than haloalkane towards nucleophilic substitution reaction. 2. Haloalkanes react with KCN to form alkyl cyanide as main product while AgCN form isocyonide. Ans. KCN is‚ predominantly ionic compound and provide cyanide ion : C N in solution. The attack mainly takes place through lone pair of electron on carbon atom due to high electron density and not through nitrogen atom since C-C bond is more stable than C-N bond. AgCN: is mainly a covalent compound therefore‚ nitrogen

Goals The main goal of this project is to learn how to identify the properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness

Process Module 1 19 Aug 1999 SRI Consulting Process Summary This Aspen Plus model simulates the production of acetic acid by low pressure methanol carbonylation in the presence of a heterogeneous rhodium (Rh) catalyst and the promoter methyl iodide. It is intended to resemble the Chiyoda/UOP Acetica™ process‚ a novel heterogeneous methanol process for the production of acetic acid. This technology is based on a heterogeneous Rh catalyst in which the active Rh complex is chemically immobilized
