The reaction between 1-bromopropane and sodium ethoxide in ethanol is an SN2 nucleophilic substitution bimolecular reaction. In this reaction, the ethoxide ion CH3CH2O- from sodium ethoxide acts as a nucleophile and attacks the electrophilic carbon the one attached to the bromine in 1-bromopropane. The bromide ion Br- leaves as a leaving group, and sodium bromide is formed as a byproduct.The major product of this reaction is propyl ethyl ether CH3CH2CH2OCH2CH3 . The reaction can be represented as follows:CH3CH2CH2Br + CH3CH2ONa CH3CH2CH2OCH2CH3 + NaBr
