- Provide the major products (write “no reaction” if you think so) for the following reactions with correct stereochemistry.arrow_forwardHow many alkenes yield 2,2,3,4,4−pentamethylpentane on catalytic hydrogenation?arrow_forwardCompounds X and Y are both C7H15Cl products formed in the radical chlorination of 2,4-dimethylpentane. Base-promoted E2 elimination of X and Y gives, in each case, a single C7H₁4 alkene. Both X and Y undergo an SN2 reaction with sodium iodide in acetone solution to give C7H15l products; in this reaction Y reacts faster than X. What is the structure of X? • Do not use stereobonds in your answer. • In cases where there is more than one possible structure for each molecule, just give one for each. . Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate structures with + signs from the drop-down menu. наarrow_forward
- 1. Bicyclic keto compounds such as camphor react predictably with nucleophiles according to steric influences; this effect has been termed steric approach control. In contrast, the reaction of nucleophiles with simple acyclic and monocyclic keto compounds are influenced primarily by thermodynamic factors; this effect has been termed product development control.
