(after aqueous workup). If no reaction occurs, draw the starting
material. There are two products of this reaction. Draw the one
that contains the saturated (nonaromatic) six-membered ring.
b) Give the major product of the following reaction (after
aqueous workup). If no reaction occurs, draw the starting material.
There are two products of this reaction. Draw the one that contains
the five-membered ring.

5. Consider the generic reaction shown below in which reactant A is converted to product B. A pure sample of reactant A is allowed to reach equilibrium. The concentrations of both A and B were monitored during this process and plotted below as a function of time. A(8)=B (8) concentration time a. Based on these data, is the value of Key for this reaction greater than or less than 1? Briefly explain how you can tell. b. The reaction is...

Draw the structure of the product of this reaction. Use the wedge hash bond tools to indicate stereochemistry. If there are alternative structures, draw the most stable one. If no reaction occurs, draw the organic starting material. Predict the major substitution products of the following reaction. Use the wedge hash bond tools to indicate stereochemistry. If there is more than one major product possible, draw all of them. Draw one structure per sketcher. Add additional sketchers using the dropdown menu...
