Carboxylic Acid Derivatives: Reactions and Mechanisms
This comprehensive guide explores... Show more
Preparation of Acyl Chlorides
This page focuses on the preparation of acyl chlorides from carboxylic acids. Acyl chlorides are an important class of carboxylic acid derivatives with the suffix "-oyl chloride".
Vocabulary: Acyl chlorides have the suffix "-oyl chloride" and are named based on the parent chain.
The preparation of acyl chlorides involves a reaction between carboxylic acids and thionyl chloride . This reaction must be carried out in a fume cupboard due to the production of toxic gases.
Example: Ethanoic acid reacts with thionyl chloride to form ethanoyl chloride: CH₃COOH + SOCl₂ → CH₃COCl + SO₂ + HCl
Highlight: The preparation of acyl chlorides from carboxylic acids produces toxic gases, including sulfur dioxide and hydrogen chloride, necessitating the use of a fume cupboard.
Reactions of Acyl Chlorides
This page discusses the reactivity and reactions of acyl chlorides. Acyl chloride reactions are characterized by their high reactivity and ease of conversion into other carboxylic acid derivatives.
Key points about acyl chloride reactions:
Definition: A condensation reaction is when two molecules react together to form larger molecules, often with the elimination of a small molecule like water or HCl.
Highlight: In acyl chloride reactions, the chlorine atom leaves as part of an elimination reaction, while the C=O double bond is retained.
Acyl Chlorides with Alcohols and Phenols
This page covers the reaction of acyl chlorides with alcohols and phenols to form esters. This is an important acyl chloride to ester transformation in organic chemistry.
The general reaction can be represented as: R-COCl + R'-OH → R-COOR' + HCl
Example: Propanoyl chloride reacts with ethanol to form ethyl propanoate: CH₃CH₂COCl + CH₃CH₂OH → CH₃CH₂COOCH₂CH₃ + HCl
The page also mentions that phenols can react similarly with acyl chlorides to form phenyl esters.
Highlight: The acid chloride and alcohol conditions for this reaction do not require a full mechanism with curly arrows, but understanding the overall transformation is crucial.
Acyl Chlorides with Water
This page discusses the reaction of acyl chlorides with water, which leads to the formation of carboxylic acids. This reaction demonstrates the acyl chloride to carboxylic acid transformation.
The general reaction can be represented as: R-COCl + H₂O → R-COOH + HCl
Example: Propanoyl chloride reacts vigorously with water to form propanoic acid: CH₃CH₂COCl + H₂O → CH₃CH₂COOH + HCl
Highlight: The acid chloride and water mechanism involves a violent reaction, producing dense steamy fumes of HCl gas.
An important observation is that this reaction produces dense steamy fumes, indicating the release of hydrogen chloride gas. Due to the reactivity with water, acyl chlorides must be handled in anhydrous conditions.
Acyl Chlorides with Ammonia and Amines
This page briefly mentions the reaction of acyl chlorides with ammonia and amines to form amides. This reaction is part of the broader category of acyl chloride reactions and demonstrates the versatility of these compounds in organic synthesis.
The general reaction can be represented as: R-COCl + NH₃ → R-CONH₂ + HCl R-COCl + R'NH₂ → R-CONHR' + HCl
Highlight: The reaction of acyl chlorides with ammonia and amines is a key method for synthesizing amides, an important class of organic compounds.
Introduction to Acid Anhydrides
This page introduces acid anhydrides, another class of carboxylic acid derivatives. Acid anhydrides are formed by the condensation of two carboxylic acid molecules with the loss of water.
Definition: Acid anhydrides are compounds derived from two carboxylic acid molecules through the loss of water.
Example: Ethanoic anhydride is formed from two molecules of ethanoic acid: 2CH₃COOH → ₂O + H₂O
The page also mentions mixed anhydrides, such as ethanoic propanoic anhydride, which are formed from two different carboxylic acids.
Highlight: The formation of acid anhydrides is an example of a condensation reaction, where two molecules combine with the loss of a small molecule .
Reactions of Acid Anhydrides
This final page covers the reactions of acid anhydrides, comparing their reactivity to acyl chlorides. Acid anhydrides undergo similar reactions to acyl chlorides but are generally less reactive.
Key reactions of acid anhydrides include:
Example: Ethanoic anhydride reacts with phenol to form phenyl ethanoate and ethanoic acid.
Highlight: Acid anhydrides are less reactive than acyl chlorides but still undergo important transformations in organic synthesis.
The page emphasizes that these reactions are part of the broader category of hydrolysis of carboxylic acid derivatives, which is a crucial concept in organic chemistry.
Introduction to Carboxylic Acid Derivatives
This page introduces carboxylic acid derivatives and their general structure. Carboxylic acid derivatives are compounds that can be hydrolyzed to form the parent carboxylic acid. The hydroxyl group in the -COOH is replaced with other functional groups. These derivatives all contain the acyl group in their structure.
Definition: Carboxylic acid derivatives are compounds that can be hydrolyzed to form the parent carboxylic acid, where the OH in -COOH is replaced with other groups.
The page illustrates various carboxylic acid derivatives, including:
Highlight: All carboxylic acid derivatives contain the acyl group in their structure.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
