- The ketone shown was prepared in a three-step sequence from ethyl trifluoroacetate. The first step in the sequence involved treating ethyl trifluoroacetate with ammonia to give compound A. Compound A was in turn converted to the desired ketone by way of compound B. Fill in the missing reagents in the sequence shown, and give the structures of compounds A and B.arrow_forwardBased on the following H NMR and IR spectrums, what is the structure of C9H8O4?arrow_forwardWhen methanitrobenzoic acid is reacted with bromomethane in the presence of Lewis acids, which of the following is the product?arrow_forward
- Give the structure of the hydroxyl compound corresponding to the following lactones.arrow_forwardCompound A is an alcohol that undergoes oxidation to produce compound B.Compound B is a ketone that gives positive triiodomethane reaction. Compound B isthen reacted with phenyl magnesium bromide, C6H5MgBr in the presence of aqueousacid to form compound C. Compound C has the molecular formula of C9H12O. Deducethe structure for compound A, B and C. PLEASE PROVIDE CLEAR DRAWINGS AND EXPLANATIONSarrow_forward2,3-Dimethylfumaric acid has a molecular formula C6H8O4. It undergoes oxidativecleavage to form two identical compound N. Compound N is then reacted withethylmagnesium bromide to form compound O. Compound O is then hydrolysed inacidic condition to form compound P. Draw the structure of compound N, O and P. PLEASE PROVIDE CLEAR HANDWRITING, and explantionarrow_forward
- Compound A is first reacted with methylamine in the presence of acid and then treated with NaBH3CN. Using the spectroscopic data given, what is the structure of the product after step 1?arrow_forwardWrite the letter that corresponds with the compound described by the following statements. Lowest rate of evolution of H2 gas evolution upon reaction with Na metal. Will react with K2Cr2O7 to form a ketone. Can be oxidized to form an aldehyde.arrow_forwardAn organic compound A of unknown structure was found to have a molecular formula C8H16. When A was poured in water and heated, compound B having a molecular formula C8H18O was formed. B upon heating with sulfuric acid was converted to C as the major product which is identical to A. Ozonolysis of C gave one molecule each of two different products D and E, both having a molecular formula C4H8O. Write the reactions involved and determine the structure of A,B,C,D and E.arrow_forward
