In alkylbenzenes, the alkyl side chain is oxidized to form carboxylic acids. The specific functional groups targeted for oxidation are the carbon-carbon bonds in the alkyl chain. Commonly employed oxidizing reagents for this transformation include chromates (e.g., chromic acid, CrO₃) and permanganates (e.g., potassium permanganate, KMnO₄). These strong oxidizing agents break the carbon-carbon bonds in the alkyl side chain, resulting in the removal of the entire side chain and the formation of a carboxylic acid group on the aromatic ring. This process is known as side-chain oxidation and is a crucial method for synthesizing aromatic carboxylic acids from alkylbenzenes.
Carboxylic acids can be obtained from nitriles through a hydrolysis reaction, often referred to as nitrile hydrolysis. The reaction is typically carried out under acidic conditions, using a strong acid such as concentrated sulfuric acid (H₂SO₄) or hydrochloric acid (HCl). The acid catalyzes the hydrRead more
Carboxylic acids can be obtained from nitriles through a hydrolysis reaction, often referred to as nitrile hydrolysis. The reaction is typically carried out under acidic conditions, using a strong acid such as concentrated sulfuric acid (H₂SO₄) or hydrochloric acid (HCl). The acid catalyzes the hydrolysis of the nitrile, initially converting it to an amide intermediate. To control the reaction and stop it at the amide stage, mild catalytic conditions with lower concentrations of acid and lower reaction temperatures are employed. This allows for a controlled and selective conversion of nitriles to amides without further hydrolysis to carboxylic acids.
Metals found in the middle of the activity series exhibit moderate reactivity and are often more stable in their elemental form. Common examples include zinc (Zn), iron (Fe), and copper (Cu).

Metals found in the middle of the activity series exhibit moderate reactivity and are often more stable in their elemental form. Common examples include zinc (Zn), iron (Fe), and copper (Cu). These metals display characteristics of both reactive and less reactive metals. They can displace ions of metals below them in the series but are not easily displaced by those above. This makes them useful in various applications, including corrosion-resistant alloys (e.g., stainless steel with iron and chromium) and sacrificial anodes (e.g., zinc anodes to protect iron structures). Their intermediate reactivity is advantageous in balancing functionality and durability in diverse industrial contexts.
Obtaining a metal from its oxide is often easier than from its sulphides or carbonates due to differences in thermodynamic stability. Metal oxides generally have lower thermodynamic stability than sulphides or carbonates. In the extraction process, metals are often reduced from their ores through aRead more
Obtaining a metal from its oxide is often easier than from its sulphides or carbonates due to differences in thermodynamic stability. Metal oxides generally have lower thermodynamic stability than sulphides or carbonates. In the extraction process, metals are often reduced from their ores through a reaction with a reducing agent. Reduction of metal oxides requires less energy compared to sulphides or carbonates. Additionally, metal oxides are more commonly found in nature, simplifying the extraction process. This makes the reduction of metal oxides a more economically feasible and energetically favorable method for obtaining metals in various metallurgical processes.
Carboxylic acids are characterized by the carboxyl functional group, which consists of a carbonyl group (C=O) and a hydroxyl group (–OH) attached to the same carbon atom.

Carboxylic acids are characterized by the carboxyl functional group, which consists of a carbonyl group (C=O) and a hydroxyl group (–OH) attached to the same carbon atom. The carbonyl group imparts polarity and reactivity, while the hydroxyl group contributes acidity. The structural composition of the carboxyl group is represented as –COOH. This group plays a crucial role in the properties and behavior of carboxylic acids, conferring them with acidic properties due to the ability of the hydroxyl group to release a proton (H⁺) in solution. Carboxylic acids are vital in various biological and chemical processes, including the formation of proteins and lipids.
