Is it right answer for B? and D E please.. Substitution/Elimination Practice 1. Please identity the type of reaction (SN1, SN2, E1, or E2) and draw the major product(s): Bryty OH NaH DMF SN2 SNI OH NaOEt HOEt ΕΑ
Short Answer Section (43 pts) – showing work helps! Substitution vs. Elimination (12 pts). Predict all major product(s) of each of the following reactions and indicate the predominant mechanistic pathways (Sn1, Sn2, E1, E2). Remember to consider rearrangements. Mechanism #1 (10 pts). Draw a stepwise mechanism to account for the following transformation. Br mechanism(s)? NaOH Cl mechanism(s)? NaOEt OTs for this reaction, circle the major product mechanism(s)? O K Cl for this reaction, circle the major product mechanism(s)? NaOCH3 H2O...
For each of the following reactions, determine which ELIMINATION mechanism (E1 or E2) will occur. Alkyl Halide Substitution: Methyl 1° 2° 3° Base Strength: Strong Weak Mechanism Type: E1 E2 Draw the mechanism that leads to ALL products for the reaction. Finally, underline the major product of the elimination reaction: H3C OH H2C H2C1 Br CHE
Key Topics: Nucleophilic Substitution Reactions (SNI or SN2. Reactions using PBr3. SOCI, or TCI. In the empty boxes, draw the structure of the MAJOR organic product expected following each reaction shown. If the reaction involves an SN2 reaction (or involves an SN2 step in the overall mechanism) clearly show the correct stereochemistry that will be observed in the product. Two of the reactions will involve a carbocation rearrangement. (4pts for each correct Major product drawn) H*, MeOH HO NaOH NaCN...
Compare and contrast SN1, SN2, E1 and E2 reactions. What are some obvious similarities and differences between each reaction pathway? What are the requirements for each reaction to work? Discuss why SN2 is in direct competition with E2 while SN1 is in direct competition with the E1 reaction pathway. What is the rate expression for each? Which reactions are concerted? Which reactions are step-wise? Which reactions are stereospecific and what is the stereospecificity of each that are? How do the...
possible Substitution and elimination can be competing reactions. Show all the elimination/substitution products of this reaction and define the type (uni or bi) NaOCH3
E1 and E2 Reactions: Predicted Ability: Good Average Poor Actual Ability: Good Average Poor When determining which mechanism (E1 or E2) occurs, the following process is helpful: 1) Determine the substitution (methyl, 1º, 2º, or 3º) of the alkyl halide 2) Determine the strength of the nucleophile Please fill out the following table, indicating the category of reaction (E1 or E2) that will occur in each set of alkyl halides and nucleophiles. If no reaction occurs, write 'NR:' Alkyl Halide...
3. Determine the mechanism of nucleophilic substitution (SNI or SN2) for each reaction and draw the products. Be aware of stereochemistry. 8 + CN - dletone m et och cun, DE Br + OCH₂ CH₂ DME 4.
