- What 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_forwardDraw structures of compounds that fit the following descriptions: a) An , unsaturated ketone, C9H8O b) An diketone c) An aromatic ketone, C9H10O d) A diene aldehyde, C7H8Oarrow_forwardDraw a resonance structure of the acetonitrile anion, -: CH2CN, and account for the acidity of nitriles.arrow_forward
- Draw the product of the following compounds with the given image. 1. A. BH3 B. H2O2, OH- 2. A. O3 B. Z2, H2O, H+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_forwardNitromethane is reacted with ethyl prop-2-enoate with EtO-Na+, EtOH 3 equivalents to give the product X(C16). X then reacts with H2/Raney Ni to give the product Y(C14), which in turn reacts with Na to give Z (C12). Indicate which products X, Y and Z are.arrow_forward
- The following product can be synthesized from the reaction of an alkene with Hg(OAc)2 followed by reduction with NaBH4. Draw all possible alkenes that will give the product shownarrow_forwardDraw the products formed when each alkene is treated with O3 followed by Zn, H2O.arrow_forwardDraw the structure of each product from the reaction of benzene with 2-chloro-1-methylcyclohexane using AlCl 3 as the catalyst and Identify the major product.arrow_forward
