Draw both resonance structures of the most stable carbocation intermediate in the reaction shown. +HCI You do not have to consider stereochemistry Do not include anionic counter-ions, e.g., I, in your answer. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate resonance structures using the +symbol from the drop-down menu.

Explain why substitution is difficult on accomplish on the benzene ring?

draw the tetrahedral intermediate as it is ormed in the following reaction. H₂C O NH₂ HCI/H₂O reflux You do not have to consider stereochemistry. Include all valence lone pairs in your answer. Do not include counter-ions, e.g., Na+, I, in your answe In cases where there is more than one answer, just draw

Among a primary, secondary, or tertiary carbocation, which is most favored for SN1 reactions? Explain why

Consider the following reaction HCI If the reaction is carried out at 40°C, what is the major product? Draw the product and the mechanistic step that leads to the product. If the reaction is carried out at 0°C, what is the major product? Draw the product and the mechanistic step that leads to the product. (hint: consider polarization of the carbocation intermediate to determine the product).

The carbocation shown here is formed in one step of an electrophilic aromatic substitution reaction (discussed in Chapter 22). (a) Draw the curved arrow notation and the product for the elimination of H*. (b) Do the same for the elimination of SO3H*. НО O: S: O= H,0 ?

Draw the least stable resonance form for the intermediate in the following electrophilic substitution reaction. CF3 CF3 Br2/FeBr3 Br . You do not have to consider stereochemistry. • Include all valence lone pairs in your answer. • In cases where there is more than one answer, just draw one. n ?

Rank the following from most reactive to least reactive in an SN1 reaction.

Curved arrows are used to illustrate the flow of electrons. Use the reaction conditions provided and follow the arrows to draw the intermediate and product in this reaction or mechanistic step(s). Include all lone pairs and charges as appropriate. Ignore stereochemistry. Ignore inorganic byproducts.
