Alcohol is a carbon-containing chemical molecule with a hydroxyl functional group attached. Alkenes, carbonyl compounds, alkyl halide hydrolysis, primary amines, alcohol fermentation, and ether hydrolysis are all sources of alcohol. As a result, there are two halves to an alcohol molecule.

The first is alkylated, while the second is hydroxylated. Alcohols are hydrocarbon derivatives with the -OH functional group, which means that a hydrogen atom has been substituted by -OH. There are three forms of alcohol: primary alcohol, secondary alcohol, and tertiary alcohol depending on the presence of hydroxyl groups in the chemical. Because the -OH group is connected to the carbon via a covalent connection, the nature of alcohol is predominantly covalent.

Ethyl alcohol is also known as ethanol and is classified as a primary or one of the main alcohols. Chemical Reactions of Alcohol Alcohol can behave as both a nucleophile and an electrophile in reactions involving alcohol. In reactions in which the link between O and H is broken, alcohols act as nucleophiles. In reactions when the connection between C and O is disrupted, alcohols can act as electrophiles.

The dehydration reaction is the answer to this question. Alcohols are dehydrated to create alkenes when heated with a protonic acid such as conc. In an acidic environment, alcohols dehydrate. Hydrolysis of Alcohols: Alcohol hydrolysis is an oxidation reaction. Water serves as a catalyst in this reaction.

The principal products of this hydrolysis process are aldehydes and ketones. An acid or a base catalyzes esterification. In oxidation reactions, this type of cleavage and bond creation takes place. Because dehydrogenation reactions include the loss of hydrogen from alcohol, they are also known as dehydrogenation reactions.

Primary Alcohol: A primary alcohol is easily oxidized to generate an aldehyde, which is followed by a carboxylic acid. The aldehyde and acid that result have the same number of carbon atoms as the parent alcohol. Secondary Alcohol: With chromic anhydride, secondary alcohol can be quickly converted to a ketone. Under extreme conditions, the ketone might be further oxidized to produce an acid mixture.

The ketone has the same amount of carbon atoms as the parent alcohol, but the acids produced have less. In the presence of an oxidizing agent, secondary alcohol is converted to the ketone. Tertiary Alcohol: Because there is no hydrogen in the carbon-bearing hydroxyl group, tertiary alcohol is extremely difficult to oxidize OH. When exposed to acidic oxidizing chemicals under very strong circumstances at very high temperatures, cleavage of various C-C bonds occurs, allowing for the oxidation of tertiary alcohol.

They combine ketones with carboxylic acids to generate ketone-carboxylic acid combinations. The 4 number of carbon atoms in ketones and acids is lower than that of the beginning alcohols. MnO2 is an oxidizer that only oxidizes the alcohol allylic, benzylic, and propargylic. Phenol Ferdinand Runge, an scientist, discovered phenol. From coal tar, he was able to extract it. Because phenol can cause chemical burns to the skin, it should be handled with caution.

Phenolic acid is a different name for this substance. A six-membered aromatic ring immediately linked to a hydroxyl group is used to identify members of this species. The phenol family includes this species, which has the formula phenol. An alkyl, alkynyl, cycloalkyl, or benzyl group could be the saturated carbon.

Phenols, on the other hand, are chemicals that have a hydroxyl group connected to a benzene ring. Phenols are formed by cumene, diazonium salts, and other compounds. Chemical Reactions of Phenol Because a hydroxyl group linked to an aromatic ring acts as an ortho-para director, phenols are extremely reactive.

Williamson Synthesis: In laboratories, this is a crucial approach for making symmetrical and asymmetrical ethers. An alkyl halide reacts with sodium alkoxide to produce ether in the Williamson synthesis. Nucleophilic Aromatic substitution Formation of Ethers : Fries Rearrangement: Oxidation to Quinones: Despite the lack of a hydrogen atom on the hydroxyl-bearing carbon, phenols are relatively simple to oxidize.

When substituents on aromatic rings are present, standard IUPAC nomenclature should be followed when naming aromatic compounds. Structure and properties[ edit ] Phenol ethers, similarly to regular ethers, are less hydrophilic than its precursors, phenols and alcohols, both of which can donate and accept hydrogen bonds. Phenol ethers, however, are still able to accept hydrogen bonds through the ethereal oxygen, allowing for its slight solubility in polar solvents.

However, the presence of the aromatic ring reduces its solubility in polar solvents such as water and ethanol. Diethyl ether has higher water solubility of 8 g per mL, versus diphenyl ether, with a solubility of 0. Preparation[ edit ] Phenol ethers can be synthesized through an acid-catalyzed condensation of phenols and an alcohol. Phenols include phenol itself, benzenediols, polyphenols, and other phenol-derived molecules. An acid catalyzed condensation between phenol and ethanol, forming ethoxybenzene.

However, this synthesis risks the self-condensation of alcohol itself e. A more common and higher-yielding reaction is the Williamson ether synthesis , where a phenol is converted by a strong base to the phenoxide ion, which can subsequently be reacted with an alkyl halide via nucleophilic substitution to form the desired phenol ether.
