Step 2b: The next step in the mechanism involves the second equivalent of ethyl ethanoate and the deprotonated first equivalent of ethyl ethanoate. The ethanol produced from the first step has been removed. More specifically, a o bond forms between a nucleophile and an electrophile. Use curved arrows to indicate the formation of a o bond.

Hello, I do not understand this questions and I am stuck. May I get help please?? Question: Draw the curved arrow mechanism for the following reaction

Draw both resonance structures of the most stable carbocation intermediate in the reaction shown.

Complete the mechanism for the base-catalyzed opening of the epoxide by adding any missing atoms, bonds, charges, nonbonding electron pairs, and curved arrows. Step 1: add curved arrows. Step 2: complete the structure and add curved arrOwS. Select Draw Rings More Erase Select Draw Rings More Erase H. H 0

How come in step 3, water doesn't attack the carbocation? Wouldn't it naturally want to immediately neutralize the carbocation instead of creating a double bond?

3) Any compound or ion with at least one lone pair can be considered a base and/or a nucleophile. The relative basicity and nucleophilicity of the species is one of the most important factors that determine the mechanism of a reaction on sp³-carbon atoms. Please show an example of a) a reagent that is a strong nucleophile and a strong base, b) a reagent that is a weak nucleophile and a strong base, c) a reagent that is a strong nucleophile and a weak base, d) a reagent that is a weak nucleophile and a weak base. Which nitrogen atom in the structure below is most nucleophilic? Please explain by discussing the electron density around each nitrogen atom. Show at least three resonance structures of the compound. N.

Draw the major organic product(s) of the following reaction. CI CH3OH NaOCH3 You do not have to consider stereochemistry. • If no reaction occurs, draw the organic starting material. • When Sy1 & E1 pathways compete, show both the substitution and the elimination products. • Separate multiple products using the + sign from the drop-down menu. • Do not include counter-ions, e.g., Na", I', in your answer.

Draw the organic product of the acid-base reaction between the species shown below. Two equivalents of –OH are used.

For the given SN2 reaction, draw the organic and inorganic products of the reaction, and identify the nucleophile, substrate, and leaving group. Include wedge-and-dash bonds and draw hydrogen on a stereocenter. Hmm.. CEN + CI Organic product Inorganic product
