- A problem often encountered in the oxidation of primary alcohols to acids is that esters are sometimes produced as by-products. For example, oxidation of ethanol yields acetic acid and ethyl acetate: Propose a mechanism to account for the formation of ethyl acetate. Take into account the reversible reaction between aldehydes and alcohols:Identify which substitution mechanism best fits the following statement: The reaction proceeds through a concerted mechanism. A) SN1 B) SN2Internal alkynes are able to selectively form one product when subjected to most reaction conditions. T or F Alkynes react with one equivalent of acid to create a carbocation for Markovnikov addition. T or F Alkynes react very similarly to alkenes. Understanding the mechanisms from chapter 12 will help understand the reaction pathways in chapter 13 where mechanisms are not explicitly drawn. T or F
