3. Two cyclic products are possible from the Dieckmann condensation shown below, but only one product forms. 1. NaOEt, EtOH EtO OEt 2. H3O+ a. Provide the product of the Dieckmann condensation shown above. b. Provide a complete mechanism, using appropriate curved arrows to show the direction of electron flow, for the Dieckmann condensation. You must show the correct formal charges on atoms at each step. You must write out the full structure of each intermediate using an accepted chemical style. Clearly indicate which steps are reversible or unidirectional with the correct reaction arrows.

4. Synthesis Using the carbon-containing starting material(s), propose a synthesis by drawing structures for all intermediates. The carbon atoms in the product must originate from the starting material(s) (or a carbene/carbenoid or CO2), but you may use as many equivalents of each starting material as you would like, and any reagent/reaction you know. (note: no mechanisms are required). OH

2. Based on the reaction arrows provided, show the expected product(s) of the reaction with appropriate charge and lone pair of electrons as needed. X B. C. H-C CH,

4. You may know salicylic acid as an ingredient in anti-acne medication, or as a precursor to aspirin. Salicylic acid is also synthesized by the following reaction: ONa OH you 1. CO₂, heat 2. H₂O* a. Draw a reasonable arrow-pushing mechanism for the formation of the product. b. The challenge: Reach back to 2311 or general chemistry to propose why the ortho position is favored over para for this product.

May you please help me with this ochem question?

Suppose you are given the starting molecule shown below. For each of the cases listed below, list the reaction conditions and reagents that would give that product, and give a brief explanation of why ONLY the specified product would be formed under the conditions you chose. Make product alcohol with OH group at carbon 1. Make product alcohol with OH group at carbon 2. Make product alcohol with OH group at carbon 3. а. b. 3 2 C.
