ORGANIC CHEMISTRY II PRACTICE QUESTIONS 1. An organic compound "A" with molecular formula ArCl on treatment with NaOH/H. results in "B".Bon treatment with Zinc dust gives an aromatic hydrocarbon "C". On further alkylation with a suitable reagent in the presence of AICI: "D" is obtained. An acid(E) is the final product of oxidation of "D". Identify A,B,C,D and give the complete equations. 2. lllutsrate a synthetic route for the preparation of p-bromoaniline from Benzene. 3. Convert Benzene to Bromobenzene (through...
[Review Topics] [References) Compounds X and Y are both CH, Cl products formed in the radical chlorination of 2,4-dimethylpentane. Base-promoted E2 elimination of X and Y gives, in each case, a single C H 4 alkene. Both X and Y undergo an Sy2 reaction with sodium iodide in acetone solution to give CH I products; in this reaction Y reacts faster than X What is the structure of X? . Do not use stereobonds in your answer. • In cases...
