To draw the structures from A to I in following synthesis scheme. Concept introduction: In nucleophilic aromatic substitution reaction, the nucleophile is substituted on the benzene ring by displacing a good leaving group. FeBr 3 does bromination of benzene gives product A. In the presence of Grignard reagent product B is formed. The epoxide ring opens to form alcohol C. Oxidized to D. After transformation gives acid chloride E. which undergoes Friedel-Crafts acylation to form ketone F, after reduction gives G which undergoes dehydration to form H. The alkene H then undergoes diels-Alder reaction to form I. NaBH 4 is a reducing reagent and capable of reducing aldehyde or ketone to primary and secondary alcohol respectively.

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.

Show that a molecule with configuration π4 has a cylindrically symmetric electron distribution. Hint: Let the π orbitals be equal to xf and yf, where f is a function that depends only on the distance from the internuclear axis.

(a) Verify that the lattice energies of the alkali metal iodides are inversely proportional to the distances between the ions in MI (M = alkali metal) by plotting the lattice energies given below against the internuclear distances dMI. Is the correlation good? Would a better fit be obtained by plotting the lattice energies as a function of (1 — d*/d)/d, as theoretically suggested, with d* = 34.5 pm? You must use a standard graphing program to plot the graph. It generates an equation for the line and calculates a correlation coefficient. (b) From the graph obtained in (a), estimate the lattice energy of silver iodide. (c) Compare the results of (b) with the experimental value of 886 kJ/mol. If they do not agree, explain the deviation.
