Relative Reactivity of Alkyl Halides Introduction Nucleophilic substitution of alkyl halides can proceed by two different mechanisms – the SN2 and the SN1. The purpose of the experiment was to identify the effects that the alkyl group and the halide-leaving group have on the rates of SN1 reactions‚ 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

1. Introduction & Case Assumptions The purpose of this Mini-case analysis is to go through the different possibilities for replacing or upgrading/overhauling ‘Vital Spark’ a cargo ship owned and operated by NETCO (The New Economy Transport Company). The part A of the case study focuses on the different options/projects available for the company to upgrade/overhaul the ‘Vital Spark’ cargo ship. The first option in this regard is to maintain existing engine and systems without installing a brand

without electricity. It is inexpensive for it is made from recyclable materials. Solar bottled light bulb is easy to assemble and the procedure use‚ in an empty clear container of soda‚ add at least 1.5 liter mineral water and 2tblespoon of liquid bleach‚ with that it will be covered half of roof sheet and exposed to sunlight. The bottle is inserted halfway through a hole drilled in the metal roof and its sides are sealed. The whole deal looks like a bulb through a sunroof and provides a good amount
