Sn2 Reaction: Preparation Of n-Butyl Bromide

| The SN2 reply-Preparation of n-butyl cliche| | | | | Name: Aasefa Shaikh date: Mon Sept. 26, 2011 capacity: Chem 3000- Organic Professor: Arturo Orellana TA: George Achonduh Name: Aasefa Shaikh Date: Mon Sept. 26, 2011 Subject: Chem 3000- Organic Professor: Arturo Orellana TA: George Achonduh Abstract The tangible com cast of n-butyl bromide from 1-butanol and sodium bromide was spy chthonic SN2 conditions. It was observed that the bromine anion, a strong nucleophile, was suitable to seafaring slope the protonated alcoholic alcoholism and displace water, which serves as a better difference correct than the hydroxide ion. The prime convoluted structure of 1- butanol allowed the bromide anion to a backside access which led to a inflection state, the appraise determining step, followed by an inversion of the reaping, n-butyl bromide. The mass of the product obtained was 6.92 grams, crowing only 33.7% portion yield. Introduction Nucelophilic substitutions atomic number 18 chemical responses in which an electron rich nucleophile assaults the electron poor electrophile1. There argon twain classes of nucelophilic reactions SN1, and SN2. The SN1 reaction is a 2 step, uni-molecular reaction, which is independent of the nucleophile.

It requires a super substituted electrophile since there is a formation of a carbocation in its straddle determining step, costly polar protic solvents which stabilize the carbocation and a good leaving group1. On the other hand, a SN2 reaction is a concerted, bimolecular reaction which has one slow, transition state1. Its habituation on the nucleophile requires that the nucleophile be electron rich so that it is able to attack and displace the leaving group. In addition, the reaction requires primary electrophiles and primary nucleophiles, which allow a backside attack to move on 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 compulsion to get a beneficial essay, order it on our website: Orderessay
