Below is a schematic representation of possible reactions that Compound X can undergo. Use the scheme to answer the following questions. What is the IUPAC name for Compound X? What type of reaction (s) is/are represented by (i) and (ii)? Compound X undergo transitions through either [A] or [B] to produce compounds [1], [2], [3] and [4]. Draw the structures of [A] and [B].
This is a problem I am struggling with, because I still struggle to understand how to accurately describe why the nitro benzene-type structure is difficult to synthesize. Please help! Also the second problem I am really struggling to put words into a problem in order to solve it. Please show all steps for both 1 and 2!
Please help illustrate the stereochemistry with dashes and wedges. Question: Draw a diastereomer for each of the following compounds: Draw the molecule on the canvas by choosing buttons from the Tools (for bonds), Atoms, and Advanced Template toolbars. The single bond is active by default. Show the appropriate stereochemistry by choosing the dashed or wedged buttons and then clicking a bond on the canvas.
Draw the structure(s) of the major organic product(s) of the following reaction. You do not have to consider stereochemistry. If a compound is formed more than once, add another sketcher and draw it again. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate multiple products using the + sign from the drop-down menu.
The above synthesis was designed using the Organic Chemistry Roadmaps in the appendix of your textbook. In this synthesis starting with acetylene, reagents from the table are used to carry out the indicated steps (shown in blue). In the box below, draw the structure of compound j. Use the wedge/hash bond tools to indicate stereochemistry where it exists. In cases where there is more than one answer, just draw one. Show stereochemistry in a meso compound. Do not include counter-ions, e.g., Na+, I-, in your answer.

In some nucleophilic substitutions under SN1 conditions, complete racemization does not occur and a small excess of one enantiomer is present. For example, treatment of optically pure 1-bromo-1-phenylpropane with water forms 1-phenylpropan-1-ol. (a) Calculate how much of each enantiomer is present using the given optical rotation data. (b) Which product predominates—the product of inversion or the product of retention of configuration? (c) Suggest an explanation for this phenomenon.
a) Which of the following is a key intermediate for Step 1 of the reaction shown in the box? (image 1) b) please name the functional groups (image 2)
