Alcohols are important for organic synthesis, especially in situations involving alkenes. The alcohol might be the desired product, or the OH group might be transformed into another functional group via halogenation, oxidation, or perhaps conversion to a sulfonic ester derivative. Formation of an alcohol from an alkene is particularly powerful because conditions can be chosen to produce either the Markovnikov or non-Markovnikov product from an unsymmetrical alkene. Using your reaction roadmap as a guide, show how to convert 4-methyl-1-pentene into 5-methylhexanenitrile. You must use 4-methyl-1-pentene and sodium cyanide as the source of all carbon atoms in the target molecule. Show all reagents needed and all molecules synthesized along the way.
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:
Consider a reaction where cis-but-2-ene is treated with OsO4 followed by NaHSO3/H2O. Draw the structure of one product that is formed in the reaction, including correct stereochemistry.
Alkenes are oxidized to give epoxides on treatment with a peroxyacid, RCO;H, such as metachloroperoxybenzoic acid (MCPBA). Peroxyacids transfer an oxygen atom to the alkene with syn stereochemistry, i.e. both C-O bonds form on the same face of the double bond, through a single step mechanism without intermediates. The oxygen atom farthest from the carbonyl group is the one transferred. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions H. CI CI HO

Under acid-catalyzed conditions, epoxides can be opened by a variety of nucleophiles other than water, such as alcohols. In such a case, the nucleophile will generally attack at the more substituted position. Using this information, predict the products for each of the following reactions (a-b): ? 1) RCO-H 2) [H₂SOJ Modify the given structure to draw the major product(s). Use the single bond tool to interconvert between double and single bonds. If a racemic mixture of enantiomers is expected, draw both enantiomers.
