The term alcohol originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic beverages.
Ethanol is only one of several types of alcohol, but it is the only type of alcohol that is found in alcoholic beverages or commonly used for recreational purposes; other alcohols such as methanol and isopropyl alcohol are toxic.

Cholesterol

The suffix -ol in non-IUPAC names (such as paracetamol or cholesterol) also typically indicates that the substance is an alcohol.
Cholesterol (from the Ancient Greek chole- (bile) and stereos (solid), followed by the chemical suffix -ol for an alcohol) is an organic molecule.

For the tertiary alcohols the general form is RR'R"COH. The simplest example is tert-butanol (2-methylpropan-2-ol), for which each of R, R', and R" is CH 3.
tert-Butyl alcohol (TBA), also called tert-butanol or t-butanol, is the simplest tertiary alcohol, with a formula of (CH 3 ) 3 COH (sometimes represented as t-BuOH).

1-Pentanol

Pentan-1-oln''-Pentanol
1-Pentanol, (or n-pentanol, pentan-1-ol), is an alcohol with five carbon atoms and the molecular formula C 5 H 11 OH.

Phenols

phenolicphenolic compoundsphenolic compound
In cases where the OH functional group is bonded to an sp 2 carbon on an aromatic ring the molecule is known as a phenol, and is named using the IUPAC rules for naming phenols.
Phenols have distinct properties and are generally distinguished from other alcohols.

Isopropyl alcohol

When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for, propan-2-ol for.
As an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms.

Such processes give fatty alcohols, which are useful for detergents.
Fatty alcohols (or long-chain alcohols) are usually high-molecular-weight, straight-chain primary alcohols, but can also range from as few as 4–6 carbons to as many as 22–26, derived from natural fats and oils.

Hydroxy group

In chemistry, alcohols are organic compounds that carry at least one hydroxyl functional group (C–OH) bound to their aliphatic substructure.
In organic chemistry, alcohols and carboxylic acids contain hydroxy groups.

The suffix -ol appears in the IUPAC chemical name of all substances where the hydroxyl group is the functional group with the highest priority.

Hydroformylation

Several species of the benign bacteria in the intestine use fermentation as a form of anaerobic metabolism.
Fermentation in food processing is the process of converting carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—under anaerobic conditions.

Oxygen

OO 2 molecular oxygen
In chemistry, alcohols are organic compounds that carry at least one hydroxyl functional group (C–OH) bound to their aliphatic substructure.
Among the most important classes of organic compounds that contain oxygen are (where "R" is an organic group): alcohols (R-OH); ethers (R-O-R); ketones (R-CO-R); aldehydes (R-CO-H); carboxylic acids (R-COOH); esters (R-COO-R); acid anhydrides (R-CO-O-CO-R); and amides.

Miscibility

Methanol, ethanol, and propanol are miscible in water.
For example, among the alcohols, ethanol has two carbon atoms and is miscible with water, whereas 1-butanol with four carbons is not.
