- Draw a resonance structure of the acetonitrile anion, -: CH2CN, and account for the acidity of nitriles.arrow_forwardWhen 2-pentene is treated with Cl2 in methanol, three products are formed. Account for the formation of each product (you need not explain their relative percentages).arrow_forwardWhen alkyne A is treated with NaNH2 followed by CH3I, a product havingmolecular formula C6H10O is formed, but it is not compound B. What isthe structure of the product, and why is it formed?arrow_forward
- Draw a resonance structure of the acetonitrile anion, :CH2C =N, and account for the acidity of nitriles.arrow_forwardWhat alkene is needed to synthesize each 1,2-diol using [1] OsO4 followed by NaHSO3 in H2O; or [2] CH3CO3H followed by −OH in H2O?arrow_forwardDevise a synthesis of (E)-tetradec-11-enal, a sex pheromone of the spruce budworm, a pest that destroys fir and spruce forests, from acetylene, Br(CH2)10OH, and any needed organic compounds or inorganic reagents.arrow_forward
- Devise a synthesis of (E)-tetradec-11-enal, a sex pheromone of thespruce budworm, a pest that destroys fir and spruce forests, fromacetylene, Br(CH2)10OH, and any needed organic compounds orinorganic reagents.arrow_forwardWhen 1-butanol is treated with conc. H2SO4 and heat .A product 'A' is formed from the reaction. Treatment of 'A' with HCl/H2O gives 'B'. Treatment of 'A' with cold KMnO4/OH- gives 'C' Treatment of 'A' with hot KMnO4 /OH- gives 'D' followed by acidification of the mixture to give 'E' 1. identify the compounds represented by A,B,C,D and E.arrow_forwardIbufenac, a para-disubstituted arene with the structure HO2CCH2C6H4CH2CH(CH3)2, is a much more potent analgesic than aspirin, but it was never sold commercially because it caused liver toxicity in some clinical trials. Devise a synthesis of ibufenac from benzene and organic halides having fewer than five carbons.arrow_forward
- Draw the organic products formed when cyclopentene is treated withfollowing reagent. [1] CH3CO3H; [2] H2O, HO−arrow_forwardDraw the products formed when phenol(C6H5OH) is treated with each reagent. Give an explanation. d. (CH3CH2)2CHCOCl, AlCl3 j. product in (d), then NH2NH2, – OHarrow_forwardOximene and myrcene, two hydrocarbons isolated from alfalfa that have the molecular formula C10H16, both yield 2,6- dimethyloctane when treated with H2 and a Pd catalyst. Ozonolysis of oximene forms (CH3)2C = O, CH2 = O, CH2(CHO)2, and CH3COCHO. Ozonolysis of myrcene yields (CH3)2C = O, CH2 = O, (two equiv), and HCOCH2CH2COCHO. Identify the structures of oximene and myrcene.arrow_forward
