- Eleostearic acid, C18H30O2, is a rare fatty acid found in the tung oil used for finishing furniture. On ozonolysis followed by treatment with zinc, eleostearic acid furnishes one part pentanal, two parts glyoxal (OHC-CHO), and one part 9-oxononanoic acid [OHC(CH2)7CO2H]. What is the structure of eleostearic acid?arrow_forwardTwo diastereomeric sets of enantiomers, A/B and C/D, exist for 3-bromo-2-butanol. When enantiomer A or B is treated with HBr, only racemic 2,3-dibromobutane is formed; no meso isomer is formed. When enantiomer C or D is treated with HBr, only meso 2,3-dibromobutane is formed; no racemic 2,3-dibromobutane is formed. Account for these observations.arrow_forwardGive the major product of the following reaction. CI AlCl3, heat Zn(Hg), HCI heat ? There is no reaction under these conditions or the correct product is not listed here.arrow_forward

- Methyl isocyanate, CH3 -N= C = O, is used in the industrial synthesis of a type of pesticide and herbicide known as a carbamate. As a historical note, an industrial accident in Bhopal, India, in 1984 resulted in leakage of an unknown quantity of this chemical into the air. An estimated 200,000 people were exposed to its vapors, and over 2000 of these people died. Q.) Methyl isocyanate reacts with strong acids, such as sulfuric acid, to form a cation. Will this molecule undergo protonation more readily on its oxygen or nitrogen atom? In considering contributing structures to each hybrid, do not consider structures in which more than one atom has an incomplete octetarrow_forwardUnder certain reaction conditions, 2,3-dibromobutane reacts with two equivalents of base to give three products, each of which contains two new p bonds. Product A has two sp hybridized carbon atoms, product B has one sp hybridized carbon atom, and product C has none. What are the structures of A, B, and C?arrow_forwardWhich of the following reactions are correct? Explain the answer. + H₂O + H₂O H₂SO4 H OH H OHarrow_forward
- What is the product for the reaction: OH + H2N хвздво A B со назыво H2N D DCC Carrow_forwardReaction of (CH3)3CH with Cl2 forms two products: (CH3)2CHCH2Cl (63%) and (CH3)3CCl (37%). Why is the major product formed by cleavage of the stronger 1° C–H bond?arrow_forwardComplete the reaction by providing the starting material/reagent/products.
