- Show how to bring about each step in this synthesis of the herbicide propranil.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_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_forward

Starting from acetylene as the starting reagent, propose a synthesis line with the reaction mechanisms involved for the synthetic obtaining of 2-heptanone and use it as a food additive in analogous cheeses.arrow_forwardWhich of the following statements is correct? A) The haloform reaction proceeds under very difficult conditions and the yield is very low. B) The haloform reaction is used only for the identification of compounds containing secondary alcohol groups. C) Methyl ketones or alcohols are oxidized with halogens in acidic solutions to give carboxylic acids and the appropriate haloform product. D) Enolate anions react rapidly with halogens to give alpha-halocarbonyl compounds.arrow_forward
