Reaction Quenching. Our cinnamaldehyde to cinnamyl alcohol reduction reaction is being quenched using HCl. Why do we use this reagent? Explain, in words and by drawing out acid/base chemistry reactions, what the quench would accomplish. Be sure to use pKa values in your explanation. HINT: there are 3 different quench reactions that occur. Look at the reagents and the mechanism for what species exist in the reaction mixture that can react with HCl. Cinnamaldehyde MW: 132.16 g/mol b.p. 248°C NaBH4, CH₂CH₂OH Diethyl Ether, 0°C OH Cinnamyl alcohol MW: 134.18 g/mol m.p. 30-33°C
Complete the mechanism for these Lewis acid-base reactions. Draw mechanistic arrows and partial charges where appropriate. Reaction A: CH₂NH₂ + HCl = 3 Reaction B: CH₂NH₂ + H₂O = 3 Reaction C: CH₂NH¯ + H₂O = 3 + Reaction D: CH₂NH 3 + H₂O 2 When each of these reactions has come to an equilibrium (where the relative amounts of each chemical species remains unchanged but the forward and reverse reactions are still occurring), predict whether each reaction will have more reactant or more product. Explain your predictions using your knowledge of atomic and molecular structures and electronegativity.

Please help me with this i am very confused, if I have a current answer it is incorrect and I am just using this to study and I am very confused
The given reaction takes place in acidic conditions under rigorous heating. Complete the reaction mechanism, adding missing atoms and lone pairs, charges, and curved arrows as necessary. Ignore hydrogen sulfate in steps 2 and 3. OH Step 1: Draw curved arrows. : он H₂SO4 A : 0: || OH : 11 Step 2: Draw a curved arrow. OH₂
For each reaction, decide whether the reaction is a redox reaction, acid-base reaction, electrophile- nucleophile, or something else. One can begin to identify the type of reaction by looking to see if oxidation numbers of atoms that take part in the reaction change during the reaction. You will need to draw out the structures. a. If the reaction is considered an acid- base reaction, draw out the full mechanism for the reaction. Be sure to indicate which compound is the acid, base, and conjugate acid and base (where possible). b. If the reaction is considered a redox reaction, be sure to indicate which species are oxidized and which are reduced. c. For every reaction you will need to justify your identification of the type of reaction.
please draw detailed mechanism. mention which one is the nucleophile, electrophile,base/ acid. Also talk about stereochemistry/ regioselectivity. In terms of stereochemistry why are we getting trans alkene. Why is the trans alkene Produced is it due choosing PPh2 as regeant? Also This reaction is the Horner wadsworth emmond wittig.
Hello, this question as two parts but they go together. Thank you, and I hope you have a nice day.
My question is asked on the picture that I am uploading, I sincerely hope Bartleby can help me more than Chegg ever did! Thank you! I need help finding the major products and minor products of the written reaction!
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.
Select the conditions in which elimination/condensation is most likely to occur. Note that only one of these needs to be present for elimination/condensation to be likely. Protic solvent Aprotic solvent Acidic conditions Basic conditions Cold Hot Shorter reaction time Longer reaction time
and II, propose a sequenced reaction, identifying the two (or more if you are bold) individual reactions and ho they would work in sequence (remember, there will not be a workup between reactions. so vou really do not want to have an acid- catalyzed reaction followed by a base-catalyzed one).
