0000 0 Question 1 Herbicides were used extensively during the Vietnam War to defoliate dense jungle areas. The concentration of certain herbicide by-products in the soil remains high today. Reactions that introduce a halogen substituent on a benzene ring are widely used, and many halogenated aromatic compounds with a range of biological activity have been synthesized. out on Generic name bupropion Trade names Wellbutrin, Zyban antidepressant, also used to reduce nicotine cravings chlorpheniramine antihistamine 2,4-D 2,4-dichlorophenoxy- acetic acid herbicide OH CI CI 2,4,5-T 2,4,5-trichlorophenoxy- acetic acid herbicide the active components in Agent Orange, a defoliant used in the Vietnam War Credit: Smith, Organic Chemistry p.729 Consider the examples of biologically active aryl chlorides.

Activated complex 400 (b) 300 Products Potential Energy (a) 200 (c) 100 Reactants Reaction Pathway Activated complex 400 (b) 300 Products Potential Energy (a) 200 (c) 100 Reactants Reaction Pathway Alex thinks that the graph above represents an exothermic reaction and the AH = +400kJ and energy will be released in this reaction. Is Alex correct? If not, find his error and then correct it with explanation. %3D

Isopentyl alcohol reacts with pure acetic acid to form isopentyl acetate, the essence of banana oil:C₅H₁₁OH+CH₃COOH⇌CH₃COOC₅H₁₁+H₂O A student adds a drying agent to remove H₂O and thus increase the yield of banana oil. Is this approach reasonable? Explain

Please ? thank you ?
