- Dibenzalpropanone is a compound that can absorb UV rays and can be used as a sunscreen. Write down the reagents used to synthesize the compound dibenzalpropanone.arrow_forward4) Multistriatin, one of the pheremones of the elm bark beetle, is a volatile compound released by a virgin female beetle when she has found a good food source - an elm tree. Male beetles, which carry the Dutch elm disease fungus, are attracted by the pheromone; the tree becomes infected with the fungus and soon dies. Multistriatin is used to trap the beetles, but the amount in beetles is so miniscule that the compound must be synthesized. The following synthesis of multistriatin uses only chemistry that we have seen in Chem 348. HO. НО Br type O type.

C6H5CH₂- Suggest two other syntheses of phenylethanoic acid, in each case indicating the starting materials and other reagents required, but not giving details of mechanism. One of your proposed syntheses must start with a compound which only contains seven carbon atoms (the acid product contains eight carbon atoms). phenylethanoic acid Phenylethanal can be converted to a hydrate in the presence of aqueous acid, though the position of equilibrium is very far to the left: H H+/H₂O OH C6H5CH₂-C-H OH Explain why…arrow_forward
- From each pair of compounds, choose the one with the indicated property and explain your choice. a) is racemized when placed in basic solution: (R)-4-methyl-2-hexanone or (R)-3-methyl-2-hexanone b) forms an enamine when treated with a ketone: diethylmethylamine or diethylaminearrow_forwardExplain the following:1. How can δ-bonds in molecules be source of electrons?2. How do base catalysts make nucleophilic reactions of carbonyl compounds faster?arrow_forwardThe analgesic Tylenol is often taken by people who are allergic to aspirin. Tylenol contains acetaminophen (structure shown) as the active ingredient. Is the structure of acetaminophen similar to the structure of aspirin? In what way? Would acetaminophen give a positive phenol test? What products would be obtained if acetaminophen were hydrolyzed in acidic aqueous solution?arrow_forward
- Draw and identity thr hybridized atoms (sp/sp2), draw reaonance structures/ polar bonds, and acidic hydrogens and basic positions for the compound Omeprazole.arrow_forwardA postgraduate student wanted to synthesized two carbonyl compounds known as compounds M and N using oxidation of alcohol. However, these carbonyl compounds should have more than 6 carbon atoms Draw two (2) possible structural formulae for compounds M and N. How would you distinguish between M and N?arrow_forwardIndicate the products A and B that are obtained in the following reactions: OH CH3 + HOCH2-CH₂OH + TSOH → A 1° NaH/THF A + →> B 2º C6H5-CH2Cl Briefly comment on each reaction.arrow_forward
- Isotretinoin is a retinoid derivative of vitamin A used in the treatment of severe recalcitrant acne. What is the degree of substitution of the encircled alkene functional group in its structure? HO, A trisubstituted monosubstituted tetrasubstituted D disubstitutedarrow_forwardAn alkene is treated with OsO4 followed by H2O2. When the resulting diol is treated with HIO4, the only product obtained is an unsubstituted cyclic ketone with molecular formula C6H10O. What is the structure of the alkene?arrow_forwardExplain the Nucleophilic substitution in the synthesis of two useful drugs ?arrow_forward
