In the nucleophilic bimolecular (SN₂) mechanism during acidic dehydration of alcohols, a protonated alcohol reacts with another alcohol molecule. The nucleophile, an oxygen atom from the second alcohol, attacks the protonated carbon, leading to the expulsion of water. This concerted process forms an ether and regenerates the acidic catalyst. This method is suitable for preparing ethers under mild acidic conditions, such as using sulfuric acid or hydrochloric acid, and is particularly effective with primary alcohols. However, steric hindrance and the presence of more substituted alcohols may favor other pathways, such as E¹ or E² reactions, yielding alkenes.
The dehydration of secondary and tertiary alcohols to form ethers is generally unsuccessful due to competing elimination reactions. In these cases, the E1 and E2 mechanisms are favored over the SN2 mechanism required for ether formation. The stability of the resulting carbocation intermediates in thRead more
The dehydration of secondary and tertiary alcohols to form ethers is generally unsuccessful due to competing elimination reactions. In these cases, the E1 and E2 mechanisms are favored over the SN2 mechanism required for ether formation. The stability of the resulting carbocation intermediates in these elimination reactions is a key factor. Secondary and tertiary carbocations are more stable than primary ones, promoting the elimination of a proton and the formation of alkenes. As a result, in the dehydration of secondary and tertiary alcohols, alkenes become the dominant products, making the synthesis of ethers less favorable under these conditions.
Methanol is primarily produced on a commercial scale through the catalytic hydrogenation of carbon monoxide (CO) with synthesis gas (syngas) derived from natural gas or biomass.

Methanol is primarily produced on a commercial scale through the catalytic hydrogenation of carbon monoxide (CO) with synthesis gas (syngas) derived from natural gas or biomass. This process, known as the low-pressure methanol synthesis, typically employs copper-based catalysts. Methanol finds applications as a solvent, antifreeze, and as a raw material in the production of chemicals like formaldehyde, acetic acid, and various plastics. It is also used as an alternative fuel source and in the synthesis of biodiesel. Additionally, methanol is employed in the production of various pharmaceuticals, detergents, and as a denaturant in industrial ethanol.
The Reimer-Tiemann reaction involves introducing a formyl group (-CHO) to the ortho position of a phenol ring.

The Reimer-Tiemann reaction involves introducing a formyl group (-CHO) to the ortho position of a phenol ring. Chloroform (CHCl₃) reacts with sodium hydroxide (NaOH) to form the chloroform anion (CHCl₂⁻) and sodium chloride (NaCl). The chloroform anion then undergoes nucleophilic attack by phenolate ion (generated from phenol by NaOH), leading to the formation of a carbene intermediate. This intermediate subsequently undergoes rearrangement and reaction with phenol, resulting in the substitution of an -CHO group at the ortho position. The Reimer-Tiemann reaction is a method for the synthesis of salicylaldehyde from phenol.
The reaction of phenol with zinc dust results in the conversion of phenol to benzene through a process known as dehydroxylation. In this reaction, zinc acts as a reducing agent.

The reaction of phenol with zinc dust results in the conversion of phenol to benzene through a process known as dehydroxylation. In this reaction, zinc acts as a reducing agent. Zinc dust reduces the hydroxyl group (-OH) in phenol to hydrogen gas (H₂) and removes the oxygen atom. The reduction of phenol to benzene involves the elimination of water (H₂O) from the hydroxyl group. This process leads to the removal of the oxygen and hydrogen from the phenolic ring, regenerating the aromaticity of benzene. The reaction with zinc dust thus facilitates the dehydroxylation and conversion of phenol to benzene.
When phenol undergoes oxidation with chromic acid (H₂CrO₄), the main product is benzoquinone (C₆H₄O₂). The oxidation typically involves the conversion of phenol to benzoquinone, which is a dicarbonyl compound.

When phenol undergoes oxidation with chromic acid (H₂CrO₄), the main product is benzoquinone (C₆H₄O₂). The oxidation typically involves the conversion of phenol to benzoquinone, which is a dicarbonyl compound. In the presence of air, the oxidation of phenols can further progress to form more highly oxidized products, such as polymeric quinones. These reactions involve the incorporation of molecular oxygen, leading to the formation of reactive intermediates and the generation of more complex oxidation products. The exact pathway and products depend on reaction conditions and the specific phenolic substrate involved.

The primary source of commercial ethanol is the fermentation of sugars. Ethanol is obtained from sugars like glucose and fructose through a process called fermentation. In this process, sugars are converted into ethanol and carbon dioxide by the action of yeast enzymes. Yeast ferments sugars in the absence of oxygen, producing ethanol and carbon dioxide as byproducts. The fermentation process is widely used in the production of alcoholic beverages and bioethanol for fuel. Additionally, industrial processes involve the fermentation of sugars derived from various sources, such as corn or sugarcane, to produce ethanol on a large scale.

Methanol, a colorless liquid, is produced via catalytic hydrogenation of carbon monoxide or destructive distillation of wood. It has a boiling point of 64.7°C, making it volatile. Methanol is used as a solvent and in fuel, antifreeze, and chemical production. However, it is highly toxic when ingested, metabolizing into formaldehyde and formic acid, causing severe health issues, including blindness and death. Its sweet taste is deceptive, as even small amounts can be fatal. Methanol poisoning requires immediate medical attention, and preventive measures, like denaturing industrial methanol, are implemented to deter its consumption.
