Preparation, reactions, Acidity, effect of substituents on acidity, structure and uses of carboxylic acid and identification tests for carboxylic acid, amide and ester
In organic chemistry, a carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom: C=O. It is common to several classes of organic compounds, as part of many larger functional groups. A compound containing a carbonyl group is often referred to as a carbonyl compound.

carboxylic acid is an organic compound containing that contains a (-COOH) as the functional group. The carboxyl group, consists of a carbonyl group attached to a hydroxyl group, hence its name carboxyl.
General formula :- RCOOH
Carboxylic acids may be aliphatic , aromatic , unsaturated etc. Some may be contain more than one carboxyl group (dicarboxylic acids, tricarboxylic acids).
Some Properties of carboxylic acids:-
Carboxylic acids are acidic in nature as the name suggest. They have a tendency to donate a proton (H+) . However they are weak acids as compared to mineral acids/ inorganic acids.Being acidic they will turn blue litmus red. This property can be used to differentiate between acidic and basic substance.
Smell :- First three aliphatic acids C1-C3 are colourless and have pungent smell. The next three acids are colourless and has unpleasant smell.
Solubility :- They are soluble in organic solvents. They are also soluble in water due to hydrogen bonding. As mass increases, the solubility decreases.

The combination of a carbonyl group and a hydroxyl on the same carbon atom is called a carboxyl group. Compounds containing the carboxyl group are called carboxylic acids. The carboxyl group is one of the most widely occurring functional groups in organic chemistry.
Aromatic Carboxylic acids: Carboxylic acids have an aryl group bound to the carboxyl group is known as aromatic carboxylic acids. The general formula of an aliphatic aromatic carboxylic acid is Ar-COOH.
Acidity of carboxylic acid:
A carboxylic acid may dissociate in water to give a proton and a carboxylate ion. Dissociation of a carboxylic acid involves breaking an O-H bond gives a carboxylate ion with the negative charge spread out equally over two oxygen atoms, compared with just one oxygen atom in an alkoxide ion. The delocalized charge makes the carboxylate ion more stable therefore; dissociation of a carboxylic acid to a carboxylate ion is less endothermic.
Preparation Methods:
1. Oxidation:
The oxidation of aldehyde with oxidizing agents such as CrO3 to forms carboxylic acids containing the same numbers of carbon atoms with a oxidizing agents like chromic acid, chromium trioxide. The silver oxide (Ag2O) in aqueous ammonia solution (Tollen’s reagent) is mild reagent give good yield at room temperature. E.g. Acetaldehyde reacts with CrO3 in aqueous acid to give acetic acid.
2. Grignard reagents (from CO2):
Carboxylic acid can be prepared by the reaction of Grignard reagent (alkyl magnesium halide) with carbon dioxide (CO2) in presence of dry ether. Grignard reagents react with carbon dioxide to forms a magnesium carboxylates which on hydrolysis by dilute HCl produces carboxylic acids.
3. Hydrolysis of nitrile:
The hydrolysis of nitrile or cyanide in presence of dilute acid to forms a carboxylic acid. In this reaction –CN group is converted to a –COOH group.
4. Hydrolysis Reactions:
All the carboxylic acid derivatives can be hydrolyzed into the carboxylic acid in the acidic or basic media; the hydrolysis reaction is fast and occurs in presence of water with no acid or base catalyst.
1. From Ester (Hydrolysis of ester): Ester can be hydrolyzed in either acidic or basic medium to yield carboxylic acid. The ester is heated with an excess of water contains strong acid or base catalyst.
Properties of Carboxylic Acids:
1. Low molecular weights carboxylic acids are colourless liquid at room temperature i.e. lower member ate liquid up to C9 and have characteristic odors whereas higher members are solid.
2. Carboxylic acids are polar organic compound. Low molecular weight carboxylic acids (first four members) are soluble in water whereas solubility in water decrease as molecular weight and chain lengthing increases.
3. Aromatic acids are insoluble in water.
4. Carboxylic acids have higher melting and boiling point due to their capacity to readily form stable hydrogen-bonded dimers.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

6. 01 Stability of Carboxylate ion
Carboxylic acids dissociate in water to form carboxylate ion and
hydronium ion. The carboxylate ion formed is stabilized
through resonance by effective delocalization of the negative
charge.
7. 01 Effect of substituent on acidity
Inductive effect: Inductive effect means polarity produces in
molecule as result of higher electronegativity of one atom compared
to another.
+I effect- If atom or groups lose/donate electron towards carbon is
said to have +I effect. Example- CH3, C2H5, 3⁰, 2⁰, 1⁰ alkyl group,
COO-
-I effect- If atom or groups which draw electron away from carbon is
said to have -I effect. Example- Cl, Br, I, F, OH, NH2, CN
8. 02 Effect of substituent on acidity
Effect of Electron releasing alkyl group (H, CH3, CH2CH3) on acidity
• This can be explained with the help of inductive effect of substituent
on alpha carbon atom
• Electron releasing alkyl group decreases the acidity
• Reason is that, electron releasing group increases the negative
charge on the carboxylate ion and destabilize it.
• The loss of proton becomes more difficult.
• As the size of alkyl group increase acidity decreases

10. 04 Effect of substituent on acidity
Effect of Electron withdrawing group (Cl, Br, F, OH, CN) on
acidity
Electron withdrawing group increases the acidity
• Reason is electronegativity of halogen, as the
electronegativity increases inductive effect increases.
Therefore less negative charge on the carboxylate ion help to
stabilize it.
• The loss of proton becomes more easy.

13. 07 Effect of substituent on acidity
Benzoic acid Versus Acetic acid
As you can see, in benzoic acid benzene ring is present which is an electron-
withdrawing group and hence it makes the 0-H bond more polar and easier to
break. This makes benzoic acid more acidic. While, there is no electron-
withdrawing group in ethanoic acid. Therefore, benzoic acid is more acidic than
ethanoic acid.
