Unformatted text preview: ~ larger Z eff equals larger nuclear attraction for electrons (7) carboxylic acids H 3 C H 2 C N H H N H H (8) esters (9) amines Naming Carboxylic acids, esters, amines (amides and ethers) Carboxylic acids contain the __________ functional group. Reactions you should know _____________ Carbon increases its bonds to oxygen (or decreases bonds to hydrogen); know the difference in oxidation products of primary alcohols (aldehyde) and secondary alcohols (ketone). Oxidation Organic chemists typically are not concerned with oxidation numbers in reactions involving carbon, rather they note movement in electron density during a reaction. Adding a more electronegative atom (such as oxygen) takes some electron density from carbon. Primary Alcohol Aldehyde Carboxylic Acid Secondary Alcohol Ketone...
