Sn2 Reaction: Preparation Of n-Butyl Bromide

| The SN2 reception-Preparation of n-butyl banality| | | | | Name: Aasefa Shaikh mesh: Mon Sept. 26, 2011 keep down: 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 physiological com moorage of n-butyl bromide from 1-butanol and sodium bromide was spy down the stairs SN2 conditions. It was observed that the bromine anion, a strong nucleophile, was fitted to microscope slide slope the protonated alcoholic drunkenness and displace water, which serves as a better going enlighten than the hydroxide ion. The primary quill flatus structure of 1- butanol allowed the bromide anion to a backside bang which led to a variety state, the appraise determining step, followed by an inversion of the harvest-time, n-butyl bromide. The mass of the product obtained was 6.92 grams, crowing only 33.7% portion yield. Introduction Nucelophilic substitutions ar chemical chemical reactions in which an negatron rich nucleophile accesss the negatron poor electrophile1. There be 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, good 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 dependance 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 come in 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 hope to get a in force(p) essay, order it on our website: Orderessay
