Abstract Alkyl halides dissolve be converted to other groups by SN1 and SN2 reactions. In this experiment, 1-butanol was converted to 1-bromobutane with the finish of achieving as close to 100% yield as possible. Factors that repair the rates of SN1 reactions, such as the leaving group, alkyl coordinate, and resultant role polarity were tested to see which has the greatest effect on the reaction rate. The percent yield of 1-bromobutane was found to be 45.4%. For the SN1 reactions, the structure was found to be the most rate controlling factor, with the 3° substrate reacting over 60x times faster than the 2° substrate. entering Halogens be highly reactive atoms that form negatively-charged stable ions1. Because of the constancy of halogens, alkyl halides can be converted to other groups through various reactions. The halide is considered a good leaving group because it can be substituted or eliminated from a compound and is stable profuse to stand on its own. Reactions that result in the production of the halide ion argon known as nucleophilic substitutions because a nucleophile replaces the halogenic leaving group.



The two types of substitutions reactions are known as SN2 and SN1. SN2 reactions are second order and are completed in a concerted step1. The nucleophile attacks the backside of the mote where the carbon atom is most exposed. The fewer alkyl groups that are attached to the central groups, the more than accessible the carbon. This explains why 1° alkyl groups (those attached to a primary carbon) are more reactive because the 3° ones (those attached to tertiary carbons) are also sterically hindered to be reactive. The carbon atom forms a partial gravel to the nucleophile while partially surrendering its bond to the leaving group (in this experiment, a halogen). This transition state gives the nucleophile and the...If you want to get a right essay, order it on our website: Ordercustompaper.com
