Alcohol | Definition, Formula, & Facts | Britannica
网页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 Alcohols may be considered as organic derivatives of water (H2O) in which a hydrogen atom has been replaced by an alkyl group.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
网页In chemistry, an alcohol (from the Arabic word al-kuḥl, الكحل) 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 sugars and cholesterol. The presence of an OH group strongly modifies ...
14.2: Alcohols - Nomenclature and Classification
网页2022年9月15日 · Name alcohols with both common names and IUPAC names. 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.
Structure and classification of alcohols - Encyclopedia Britannica
网页Alcohol - Organic Compounds, Structure, Classification: 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: Alcohols- Preparation, Classification and Uses of Alcohols ...
网页Alcohols are the compounds of the general formula R – OH, where R is an alkyl or a substituted alkyl group. Thus, alcohols are the derivatives of alkanes in which one or more H atoms are replaced by -OH. Alcohols are very important industrial chemicals. Ethanol is widely used as an antiseptic in the form of a rectified spirit.
Types of Alcohols - Primary, Secondary & Tertiary Alcohols
网页Alcohols are those organic compounds which are characterized by the presence of one, two or more hydroxyl groups (−OH) that are attached to the carbon atom in an alkyl group or hydrocarbon chain.
Alcohol - Boiling Point, Solubility, Flammability | Britannica
网页Alcohol - Boiling Point, Solubility, Flammability: Most of the common alcohols are colourless liquids at room temperature. Methyl alcohol, ethyl alcohol, and isopropyl alcohol are free-flowing liquids with fruity odours. The higher alcohols—those containing 4 to 10 carbon atoms—are somewhat viscous, or oily, and they have heavier fruity odours.
Alcohols - Chemistry LibreTexts
网页2023年1月23日 · Alcohols are molecules containing the hydroxy functional group (-OH) that is bonded to the carbon atom of an alkyl or substituted alkyl. The hydroxy functional group strongly contributes to the physical properties of alcohols.
10.1 Structure and Classification of Alcohols
网页Alcohols 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.
Alcohol Functional Group - ChemTalk
网页Quick Facts on Alcohols. Structure: A carbon single bonded to an oxygen that’s single bonded to a hydrogen; General formula: R-OH or ROH; pH: Neutral (around 7). Alcohols are generally weak acids whose most acidic proton is the H of the OH. pKa: Generally from 15 to 20. Methanol (CH 3 OH): 15.3; Ethanol (C 2 H 5 OH): 15.9; Phenol (C 6 H 5 OH ...
