Reaction Quenching: Our Fisher Esterification reaction is being quenched using sodium bicarbonate Why do we use this reagent? Explain, in words and by drawing out acid/base chemistry reactions, wha the quench would accomplish. Be sure to use pKą values in your explanation. HINT: there are 2 different quench reactions that occur. Look at the reagents and the mechanism for what species exis in the reaction mixture that can react with sodium bicarbonate. OH Isobutyric acid C4H8 02 MW: 88.11 g/mol + HO Isobutyl alcohol C4H10O MW: 74.12 g/mol H₂SO4 (cat.) Reflux O Isobutyl isobutyrate C8H1602 MW: 144.20 g/mol + H₂O

Please help with the retrosynthesis of this target molecule. Thank you!
Could you write out the mechanism for this sequence?
Please draw PLP-dependent mechanisms for this reaction. General acids/bases may be involved as needed
Identify the 5 nucleophilic sites on the straight chain and then explain which site is the most nucleophilic, do that for the electrophiles as well. There should be 3 electrophilic sites on the straight chain and 1 on the Br2. also show the arrow mechanism for this synthesis please.
Organic Chemistry Write down the retrosynthetic pathway using the principle of disconnection and FGI from the following molecular targets and then write a synthesis scheme that can be done ( answers in paper with complete explanation is needed because im new at this part, thank you )
Can someone help me with retro - synthesis, also can you do a detailed step by step with mechanisms to help me understand how you got the answer and what each reagent does.
Can you please help find the reagent and intermediate for this problem and what the meta direction would be?
In benzoic acid, when it has a deactivating group in position "para" (relative to carboxylate position) , it attracts electrons towards it, weakening the acid and an activator pushes the electrons making the acid stronger.What happens to this benzoic acid if it has a substituent at the "meta" or "ortho" position as an activator or a deactivator? I need an explanation of what happens in each case please
The product in this reaction is basic enough to be protonated by a dilute HCl solution. Draw the protonated species, clearly showing where protonation occurs. Draw all possible resonance structures of the conjugate acid of the product, and use these to explain why the product is so much more basic than a typical ester, like ethyl acetate.
Circle the molecule tht would form in the following reaction and show the mechanism
Hi, I need help to perform a retrosynthetic analysis and then to design a synthesis plan. Can you answer my question in more detail? In the RSA should all disconnections, synthons, and synthetic equivalent be shown. Can you do that step by step?
Retrosynthesis. Consider the following molecule on the left. Using only the precursors on the right and any other reagent for your transformation(s), provide a workable synthesis pathway to said target molecule.
