- 2,4-D is a synthetic auxin (a plant hormone) used in the control of broadleaf weeds, and one of the most widely used herbicides in the world. It is produced commercially by the following reaction: chloroacetic acid + dichlorophenol → hydrochloric acid + 2,4-D C2H3ClO2 + C6H4Cl2O → HCl + C8H6Cl2O3 How much chloroacetic acid does it take to manufacture 5.18 grams of 2,4-D?arrow_forwardG.152.arrow_forward5) Limonene is a compound found in orange oil and lemon oil with molecular formula C₁0H16- When limonene is treated with 1 equivalent of mCPBA, the product is limonene oxide as depicted below. When limonene is treated with excess ozone (03) and then with dimethylsulfide (Me₂S), one of the organic products of the reaction is formaldehyde. Of the structures below, which correspond to the structure of limonene and/or the structure of the other major organic product when limonene is reacted with O3 and Me₂S? Please select any and all that apply. A) 'Н H B) ? H 1) 03 (XS) 2) Me₂S (xs) ? limonene, C10H16 D) mCPBA (1 equiv) E) limonene oxide None of the abovearrow_forward
- Proteases are enzymes that can break covalent bonds in proteins. Proteases play major roles in the regulation of biological processes, so compounds that inhibit their function, called protease inhibitors, have potential as therapeutic agents. While preparing several potential protease inhibitors, compound 1 was converted into compound 3 via alkyne 2, as shown. (J. Org. Chem. 1989, 54, 3963- 3972) Draw the structure of alkyne 2, and propose reagents for converting 1 into 3. Step 1 Br Br Ph alle Br Br Edit Drawing OH Modify the given structure of 1 to draw alkyne 2. An eraser is available, and you can use the single bond tool to add/remove pi bonds. OH 2 Ph O ell (-10) Ph = 3 OHarrow_forwardWhat is(are) the major Organic product(s) in the following reaction?

- Two substitution products result from the reaction between 3-chloro-3-methyl-1- butene with sodium acetate (CH3COO – Na +) in acetic acid under SN1. Identify the products.arrow_forwardG.115. I need all three sub parts .....arrow_forwardGive reasons: (i) C—Cl bond length in chlorobenzene is shorter than C—Cl bond length in CH3—Cl.(ii) The dipole moment of chlorobenzene is lower than that of cyclohexyl chloride.(iii) SN1 reactions are accompanied by racemization in optically active alkyl halidesarrow_forward
- (a) Account for the following :(i) Electrophilic substitution reactions in haloarenes occur slowly.(ii) Haloalkanes, though polar, are insoluble in water.(b) Arrange the following compounds in increasing order of reactivity towards SN2 displacement:2-Bromo-2-Methylbutane, 1-Bromopentane, 2-Bromopentanearrow_forwardAn optically active monoterpene (compound A) with molecular formula C10H18O undergoes catalytic hydrogenation to form an optically inactive compound with molecular formula C10H20O (compound B). When compound B is heated with acid, followed by reaction with O3 and then with dimethyl sulfide, one of the products obtained is 4-methylcyclohexanone. Give possible structures for compounds A and B.arrow_forwardPyrethrin II and pyrethrosin are two natural products isolated from plants of the chrysanthemum family. Pyrethrin II is a natural insecticide and is marketed as such. Q, Calculate the index of hydrogen deficiency for each of these natural productsarrow_forward
