Why does the Hell-Volhardt-Zelinsky reaction only work for acyl halides and not other carboxyl derivatives?

The reactivity sequence of carboxylic acid derivatives (acyl halides, anhydrides, acids, esters, amides) changes with the substituent. Acyl chlorides are most reactive, amides are least reactive. 1) Explain in detail why the reactivity changes in that sequence, 2) Where do carboxylates fit in that sequence and why? How does that impact on the way carboxylic acid reactions need to run? 3) Where do thioesters, RC(-O)SMe and acyl phosphates, RC(-O)OPO2OR fit in that sequence. Explain your decision

Nucleophilic Acyl Substitution Nucleophilic Acyl Substitution is a major reaction for acids and acid derivatives. This is the reaction that converts one derivative into another. The substitution can occur in basic or acidic condition, depending on a derivative. Nucleophilic Acyl Substitution in Basic Conditions-general mechanism NUCLEOPHILIC ATTACK LOSS OF A LEAVING GROUP Nue Nuc Nuc Note: in cases when the nucleophile is neutral (H20, ROH,RNHzl, the mechanism includes one more step: deprotonation of an already attached Nuc: group by another...

Why are acyl chlorides the most reactive of all the carboxylic acid derivatives? A. Acyl chlorides have the best leaving group of all the derivatives B. The leaving group of an acyl chloride is the strongest base of all the derivatives C. Acyl chlorides have more resonance structures than the other derivatives D. Acyl chlorides have higher boiling points than the other derivatives A B C D

Provide a detailed mechanism for each part of the Hell-Volhard-Zelinsky Reaction below. Note that this reaction is covered in our textbook (among many sections) and that the reaction conditions are modified slightly. Be sure to account for this and be as detailed in every step as possible. Do not create reagents that are not made logically in the pathway (no HBr essentially so it's a "neutral" pathway). Include all curved arrows, reaction arrows, reaction intermediates, formal charges, and any other...

2. Not only does an aromatic ring itself affect the reactivity of an acid derivative (an ester, on last year's quiz), substituents on the aromatic ring can further modify the reactivity. First, we will consider a phenyl amide with a para-acetyl substituent: CH, (a) What is the n-effect (resonance) of the para-acetyl substituent? How will that affect the reactivity of the other (amide) carbonyl in the molecule below (increase or decrease, compared to the same amide but with no p-...
