- Consider the molecule given below. In theory, there are only two inequivalent hydrogens in this molecule that could be substituted by Br in a free radical bromination – circle them. Put an asterisk to mark the one most likely to be substituted first. However, there are 5 possible products from free radical bromination. Draw all the products and show using arrow formalism how the intermediate radicals leading to these products formedarrow_forwardWhat is the complete mechanism using curved arrow formalism of the two products shown below? Explain why one is major and the other is minor product formation.arrow_forwardWhen this alkene is subjected to the conditions shown, two equivalents of a single product is formed.Draw the structure of the product that would be in the box to the rightarrow_forward
- Identify compounds S and T, which are stereoisomers and provide a curved arrow mechanism that accounts for the formation of the major product. Can you also explain how you decide the major and minor product and if that method can be applied to other questions in deciding which is major/minor product. thank youarrow_forwardWhen the depicted alkyne is treated first with sodium amide and then with the alkyl halide shown, one of the depicted products is formed Circle the correct product and write the steps in the mechanism that show how this reaction occurs to form the product you selected. Add the following A. all necessary curved arrows B. the structure of any intermediates that are formed during the mechanism, including stereochemistry C, what, if anything, is added or lost during each step of the mechanism, D any nonzero formal charges. Only use materials those that are given in the equation.arrow_forwardSketch all the products of the following reaction pathway with their correct stereochemistry, if applicable.arrow_forward
- Draw the missing major organic product(s) for each of the following reactions (do not write “+ en” as a product and remember stereo- and regiochemistry!). If no reaction occurs, write “NR”.arrow_forwardChlorine and bromine react in the dark with alkenes. The reaction shown below affords a single major product as a racemic mixture. For the mechanism step below, draw curved arrows to show electron reorganization. Consider the formation of just one of the product stereoisomers. I am not sure if I have the arrows correct in this reaction: (see picture)arrow_forwardIn the given condensed formula, I understand that there will be a carbocation rearrangement due to excess hydrogen and an E1 mechanism, however, I have trouble in understanding where this bond between the nucleophile and electrophile is formed.arrow_forward
- Using Curved Arrow Formalism, draw the reaction of 1-methylcyclopentanol treated with aqueous sulfuric acid and identify the rate determining step. If more than one product is formed, identify which is major, minor, very minor, etc. Thank you for the help with this question. I appreciate it.arrow_forwardFor each of the following reactions draw the structure of the major organic product in the box provided.Each numbered set of reagents above or below the arrow represents a complete separate reaction.For multi-step reactions give only the structure of the final product.arrow_forwardDraw the mechanism and major product for each of the following Diels–Alder reactions. Pay attention to stereochemistry.Hint: You may need to consider conformations and orientations other than the ones shown.arrow_forward
