[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...
