- Three isomeric pentanols with unbranched carbon chains exist. Which of these isomers, upon dehydration at 180C, yields only 1-pentene as a product?arrow_forwardStarting with the following compounds, outline a practical synthesis of 1-butanolarrow_forwardProvide the sequence to complete the synthesis of cyclohexanol to cis-1,2-cyclohexandiol.arrow_forward
- Starting with benzene and using any other necessary reagents of your choice, what are the possible syntheses for the following compound?arrow_forwardEthers can often be prepared by SN2 reaction of alkoxide ions, RO*, with alkyl halides. Which of the two possible routes would be the better choice to synthesize the molecule shown below? Explain briefly.arrow_forwarda. Compound X is benzene, Y is acetic anhydride acid. Complete the following scheme and determine Z! b. Determine which reagents except acetic acid anhydrides can replace Y!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? Draw any relevant structures to support youranswer.arrow_forwardA hydrocarbon (X), with the molecular formula: C8H14 is reduced in presence of sodium and liquid ammonia to give the only product (Y) with the molecular formula: C8H16. Compounds X and Y both resulting 2,5-dimethylhexane when treated with hydrogen and platinum catalyst (H2/Pt). As a result of the oxidative cleavage of compound Y (by using KMnO4 / H2SO4), a single carboxylic acid derivative with C4H8O2 molecular formula is formed. Again, as a result of the reaction of Y with perbenzoic acid, the chiral compound C8H14O is observed, but the reaction of compound Y with bromine gives the achiral C8H14Br2 as the product.arrow_forwardPlease be clear in your writing, solve step by step Compound A (C9H12), when hydrogenated by catalysis on Pd / C, absorbs 3 equivalents of H2 to give compound B (C9H18). Ozonolysis of compound A gives cyclohexanone (C6H10O). Compound A reacting with NaNH2 / NH3 followed by addition of CH3Br gave compound C (C10H14). What are the structures of compounds A, B, and C?arrow_forward
- Suggest how you would synthesize each compound, use cyclopentanone as one of the reagentsarrow_forwardWhen 2-methyl-2, 5-pentanediol is treated with sulfuric acid, dehydration occurs and 2, 2-dimethyltetrahydrofuran is formed. Suggest a mechanism for this reaction. Which of the two oxygen atoms is most likely to be eliminated, and why?arrow_forwardAn organic compound A of unknown structure was found to have a molecular formula C8H16. When A was poured in water and heated, compound B having a molecular formula C8H18O was formed. B upon heating with sulfuric acid was converted to C as the major product which is identical to A. Ozonolysis of C gave one molecule each of two different products D and E, both having a molecular formula C4H8O.
