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

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.

Please help

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.

What is the product of the following reaction shown below? In class we discussed that the reaction mechanism did not go through the traditional carbocation intermediate. Draw the structure of the key reactive intermediate that occurs and explain why you get the stereochemistry on the final product. Br2

(c) Draw the mechanism of the following substitution reaction using good curved arrow notation and demonstrating the stereochemistry of the intermediate(s) and product(s). Draw the potential energy diagram, including the transition state(s). State the predominant mechanism (SN1 or S2). Describe the optical activity. Br NaN3 ethanol
