Suppose the alkene in the drawing area below is put in strong acid solution, for example a solution of HBr.
Highlight each carbon that might become protonated to form a carbocation intermediate. (The carbocation intermediate might then react with something
else to form a final product.)
سعد
Alkynes do not react directly with aqueous acid as do alkenes, but will do so in the presence of mercury(II) sulfate as a Lewis acid catalyst. The reaction occurs with Markovnikov
regiochemistry, so the OH group adds to the more highly substituted carbon and the H adds to the less highly substituted carbon. The initial product of the reaction is a vinyl alcohol, also called
an enol. The enol immediately rearranges to a more stable ketone via tautomerization.
Draw curved arrows to show the movement of electrons in this step of the mechanism.

3) A common practice that organic chemists work on is a process known as retrosynthesis.
In this a chemist will take known reactants and devise a synthetic pathway to produce
the desired products using reactions that they know. As you proceed through organic
chemistry you will be tasked with thinking about this process. How would you make the
desired final product starting from the alkyne. It will take a couple of reactions. Please
show the reagents necessary. And for your last step please show the arrow pushing.

- Write the products of the following sequences of reactions. Refer to your reaction road-map to see how the combined reactions allow you to navigate between the different functional groups.arrow_forwardA 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:arrow_forwardFollowing is the structural formula of the tranquilizer meparfynol (Oblivon). Propose a synthesis for this compound starting with acetylene and a ketone. (Notice the -yn- and -ol in the chemical name of this compound, indicating that it contains alkyne and hydroxyl functional groups.)arrow_forward

- Show the structures of all possible acid-catalysed dehydration products of the following. Where more than one alkene is possible, indicate which one will be formed in the largest amount. a) Cyclohexanol b) 2-butanol c) 1-methylcyclopentanolarrow_forwardDraw the overall reaction of 2-bromo-2-methylpropane with H2O to give the alcohol product. Include all by-products that form.arrow_forwardAlcohols are very useful organic compounds because there are many ways to synthesize larger and more complex molecules starting with simple alcohols. The reactions you will examine form a strong basis for synthetic tools that an organic chemist would use. You will be expected to predict the major products of reactions under the conditions given. The key to doing this is to look carefully at the conditions and remember how those conditions affect the products. It is a good idea to have an index card file of the reactions as you learn them. Dehydration (loss of water) - There are two forms of dehydration reactions with alcohols - ether formation and elimination (alkene formation). In both reactions you are looking for the components of water (OH and H) that will be removed in the reaction. Ether Formation - Two alcohols will form an ether link by loss of water forming an ether product with an acidic catalyst (typically H2SO4) at 140\deg C. One alcohol loses the hydroxyl group and one…arrow_forward
- The nitro groups on the benzene ring in the reactant serve two purposes.One is to let you know what atoms in the reactant correspond to what atomsin the product. But what role do the nitro groups play electronically – whywould the reaction be much slower if these nitro groups weren’t attached tothose benzene carbons?
