It was observed that the bromine anion, a strong nucleophile, was able to glide slope the protonated alcoholic jollify and displace water, which serves as a better leaving categorize than the hydroxide ion. The primary winding structure of 1- butanol allowed the bromide anion to a backside encounter which led to a vicissitude state, the appraise determining step, followed by an inversion of the crossing, n-butyl bromide. The mass of the product obtained was 6.92 grams, crowing only 33.7% percent yield. Introduction Nucelophilic substitutions are chemical reactions in which an electron rich nucleophile attacks the electron poor electrophile1. in that location are twain classes of nucelophilic reactions SN1, and SN2. The SN1 reaction is a 2 step, uni-molecular reaction, which is main(a) of the nucleophile.

It requires a super substituted electrophile since there is a formation of a carbocation in its straddle determining step, darling polar protic solvents which modify the carbocation and a good leaving group1. On the other hand, a SN2 reaction is a concerted, bimolecular reaction which has one slow, convert state1. Its dependence on the nucleophile requires that the nucleophile be electron rich so that it is able to attack and displa! ce the leaving group. In addition, the reaction requires primary electrophiles and primary nucleophiles, which allow a backside attack to occur without create steric hindrance4. The backside attack promotes inversion of the product. alkyl halides (R-X) are chemical compounds, which have a halogen atom in the position of total heat (H) 1....If you want to get a full essay, order it on our website: OrderEssay.net
