- Ethylene oxide is the starting material for the synthesis of 1,4-dioxane. Propose a mechanism for each step in this synthesis.arrow_forward(a) Give an acceptable name for each compound, (b) Draw the organic products formed when A or B is treated with each reagent: [1] H3O+; [2] −OH, H2O; [3] CH3CH2CH2MgBr (excess), then H2O; [4] LiAlH4, then H2O.arrow_forwardWhat products are formed when the following compounds react with CH3MgBr, followed by the addition of dilute acid? Disregard stereoisomers.arrow_forward
- H3C. H3C. CH3 nnc» XT :OH 2 CH₂OH HCI catalyst Aldehydes and ketones react reversibly with two equivalents of alcohol in the presence of an acid catalyst to give acetals. Alcohols are poor nucleophiles, and so protonation of the carbonyl oxygen is used to make the carbonyl carbon a stronger electrophile. Addition of the first equivalent of alcohol gives a hemiacetal, a hydroxyether. Addition of the second equivalent of alcohol is accompanied by loss of water to yield the product acetal. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions CH3 H3C CH3OH H3CQ OCH3 CH3 H3C. H HO: :OCH 3 CH3 46arrow_forwardDevise a synthesis of 1-phenyl-5-methylhexane [C6H5(CH2)4CH(CH3)2] from acetylene, alkyl halides, and any required inorganic reagents.arrow_forwardDraw all of the substitution and elimination products formed from the given alkyl halide with each reagent: (a) CH3OH; (b) KOH. Indicate the stereochemistry around the stereogenic centers present in the products, as well as the mechanism by which each product is formed.arrow_forward
- Treatment of a hydrocarbon A (molecular formula C9H18) with Br2 in the presence of light forms alkyl halides B and C, both having molecular formula C9H17Br. Reaction of either B or C with KOC(CH3)3 forms compound D (C9H16) as the major product. Ozonolysis of D forms cyclohexanone and acetone. Identify the structures of A–D.arrow_forwardComplete the following reactions by providing the correct product(s), starting materials, or reagents. When appropriate, products should have the correct stereochemistryarrow_forwardPrepare the following compounds using cyclohexane as the starting material OH COOH b. „CH;OH CH,NH2 d. CH;CH,OH „CHCH, a.arrow_forward
- Draw the products formed when the following alkynes are treated with each set of reagents: [1] H2O, H2SO4, HgSO4; or [2] R2BH followed by H2O2, −OH.arrow_forwardWhen alkyne A is treated with NaNH2 followed by CH3I, a product having molecular formula C6H10O is formed, but it is not compound B. What is the structure of the product, and why is it formed?arrow_forwardPropose two different methods to synthesize 1-octen-3-ol [CH3(CH2),CH(OH)CH=CH] using a Grignard reagent and a carbonyl compound. 1-Octen-3-ol is commonly called matsutake alcohol because it was first isolated from the Japanese matsutake mushroom.arrow_forward
