See if you can recognize the bonds broken and formed. Sodium ethoxide may either deprotonate the α-position of an ester molecule forming an enolate or the ester molecule may undergo a nucleophilic substitution called transesterificationIf the starting material is an ethyl ester trans-esterification is irrelevant since the product is. The less highly substituted alkene predominates with potassium t-butoxide because the t-butoxide ion is sterically hindered.

Since the S N 2 mechanism proceeds through a single step where the nucleophile performs a backside attack on the alkyl halide the only thing stopping this is steric hindrance. 1 1-bromohexane sodium ethoxide in ethanol 2 2-chlorohexane NaOCH3 in methanol 3 2-chloro-2-methylbutane NaOCH2CH3 in ethanol. Application 1R2R—12-Diaminocyclohex ane may be used to prepare.
