Alcohol | Definition, Formula, & Facts | Britannica
Web6 days ago · Alcohol, any of a class of organic compounds with one or more hydroxyl groups attached to a carbon atom of an alkyl group. Alcohols may be considered as organic derivatives of water (H2O) in which a hydrogen atom has been replaced by an alkyl group. Examples include ethanol, methanol, and isopropyl alcohol.
Alcohol (chemistry) - Wikipedia
WebIn chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl ( −OH) functional group bound to a saturated carbon atom. [2] [3] Alcohols range from the simple, like methanol and ethanol, to complex, like sugar alcohols and cholesterol.
14.2: Alcohols - Nomenclature and Classification
WebSep 15, 2022 · An alcohol is an organic compound with a hydroxyl (OH) functional group on an aliphatic carbon atom. Because OH is the functional group of all alcohols, we often represent alcohols by the general formula ROH, where R is an alkyl group. Alcohols are common in nature.
10.1 Structure and Classification of Alcohols - Chemistry …
WebAlcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. Alcohols fall into different classes depending on how the -OH group is positioned on the chain of carbon atoms. There are some chemical differences between the various types. Primary alcohols.

WebJan 23, 2023 · Alcohols are one of the most important molecules in organic chemistry. They can be prepared from many different types of compounds, and they can be converted into many different types of compounds. Alcohols are molecules containing the hydroxy functional group (-OH) that is bonded to the carbon atom of an alkyl or substituted alkyl.
Structure and classification of alcohols - Britannica
WebStructure and classification of alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. ( See chemical bonding for a discussion of hybrid orbitals.)
Alcohols (video) | Khan Academy
WebAlcohols, like water, can show either acidic or basic properties at the -OH group. With a pKa of around 16-19, they are, in general, slightly weaker acids than water, but they are still able to react with strong bases such as sodium hydride or reactive metals such as sodium.
an introduction to alcohols - chemguide
WebINTRODUCING ALCOHOLS. This page explains what alcohols are, and what the difference is between primary, secondary and tertiary alcohols. It looks in some detail at their simple physical properties such as solubility and boiling points. Details of the chemical reactions of alcohols are described on separate pages.
Characteristics of alcohol | Britannica
Webalcohol, Any of a class of common organic compounds that contain one or more hydroxyl groups (―OH) attached to one or more of the carbon atoms in a hydrocarbon chain. The number of other substituent groups (R) on that carbon atom make the alcohol a primary (RCH 2 OH), secondary (R 2 CHOH), or tertiary (R 3 COH) alcohol.
