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.
