Concept explainers
Interpretation:
Each reacting species is to be labeled as either “electron rich” or “electron poor”. Appropriate curved arrows are to be drawn, and the type of the elementary step is to be named under the each reaction arrow for the given reaction.

- Drawing the Product(s) of a Mechanistic Step. For the reactions that have TWO starting materials, indicate/label which species is the nucleophile and which isthe electrophile. Then, by following the curved electron-pushing arrows, draw the product(s) of the following reaction steps. Finally, identify and label what type of elementary step is represented for each mechanism.arrow_forwardPredict the relative rates of these reactions. That is, select 1 next to the reaction with the fastest rate, 2 next to the reaction with the next fastest rate, and so on. Note for advanced students: you may assume these reactions all take place in a polar aprotic solvent, like DMSO. ( Choose one) Predict the relative rates of these reactions.

- Show the mechanism for the given reaction conducted at -5 °C in CCI,. cyclohexene + bromine → dibromocyclohexane Draw structures, including charges and electrons, and add curved arrows. Details count. Draw each species (organic and inorganic) resulting from the previous step. Then, add curved arrows for the forward reaction. Include charges and nonbonding electrons. Add curved arrows to the first step. : Br - Br : Draw the major product. Include charges and nonbonding electrons.arrow_forwardDraw the products for the addition reactions below in the boxes. Then, draw the FULL electron-pushing mechanism for the reactions, including all intermediates (with formal charges and lone pairs of electrons) and all electron pushing arrows. Label the electrophile and nucleophile in each step.arrow_forwardWould these be the correct mechanism arrows for this reaction?arrow_forward
- Can you help me draw the mechanism arrows for this reaction and determine if the reaction is going forward or reverse?arrow_forwardChemistry Please also include the mechanism. Make sure to include the major products and any stereochemistry. For each arrow, there are 2 steps involved include those steps.arrow_forwardSame reaction as in Q1. H3PO4 Choose all intermediates that are formed during the reaction. Carbocation O Alkoxide Oxonium No intermediates are formedarrow_forward
- In the first box, draw the tetrahedral intermediate involved in this reaction.In the second box, draw the product of the reaction.Include all lone pairs of electrons and nonzero formal charges. Do not add curved arrows.arrow_forwardThe following reaction, which is discussed in Chapter 8, is an example of a unimolecular nucleophilic substitution (Sn1) reaction. It consists of the four elementary steps shown here. For each step (i-iv), (a) identify all electron-rich sites and all electron-poor sites, (b) draw in the appropriate curved arrows to show the bond formation and bond breaking that occur, and (c) name the elementary step.
