Question

During dehydrohalogenation of 2-bromopentane through E2 mechanism sodium ethoxide is used. Is the sodium ethoxide a base or nucleophile in this case

Expert Solution

Step 1

Elimination reactions are the reaction in which alkenes are prepared. In this two substituents are eliminated by either one step or two step mechanism.

Elimination reactions is favored, when strong base is used and substitution is favored, when nucleophile is used.

In an E2 mediated elimination reaction of an alkyl halide (H-X) using NaOCH3 as base, which of the following statement is not true?

O The rate is independent of the leaving group.
Br Brz CH3 CH3 H3C CH2CI2 H3C Br Electrophilic addition of bromine, Br2; to alkenes yields a 1,2-dibromoalkane. The reaction proceeds through a cyclic intermediate known as a bromonium ion. The reaction occurs in an anhydrous solvent such as CH,Cl). In the second step of the reaction, bromide is the nucleophile and attacks at one of the carbons of the bromonium ion to yield the product. Due to steric clashes, the bromide ion always attacks the carbon from the opposite face of the bromonium ion so that a product with anti stereochemistry is formed.
