Alcohol vs. Aldehyde

Alcoholnoun

Any of a class of organic compounds (such as ethanol) containing a hydroxyl functional group (-OH).

Aldehydenoun

(organic compound) Any of a large class of reactive organic compounds (R·CHO) having a carbonyl functional group attached to one hydrocarbon radical and a hydrogen atom.

Alcoholnoun

(colloquial) Ethanol.

Aldehydenoun

A colorless, mobile, and very volatile liquid obtained from alcohol by certain processes of oxidation.

Alcoholnoun

(uncountable) Beverages containing ethanol, collectively.

Aldehydenoun

Any compound having the group -CHO. Methyl aldehyde, the simplest aldehyde, is more commonly called formaldehyde, H-CHO, and acetic aldehyde is now more commonly called acetaldehyde. The higher aldehydes may be solids. A reducing sugar typically contains the aldehyde group.

Alcoholnoun

(obsolete) Any very fine powder.

Aldehydenoun

any of a class of highly reactive chemical compounds; used in making resins and dyes and organic acids

Alcoholnoun

An impalpable powder.

Aldehydenoun

an organic compound containing the group —CHO, formed by the oxidation of alcohols. Typical aldehydes include methanal (formaldehyde) and ethanal (acetaldehyde).

Alcoholnoun

The fluid essence or pure spirit obtained by distillation.

Aldehyde

Chemically, an aldehyde is a compound containing a functional group with the structure −CHO, consisting of a carbonyl center (a carbon double-bonded to oxygen) with the carbon atom also bonded to hydrogen and to any generic alkyl or side chain R group. The functional group itself (i.e.

Alcoholnoun

Pure spirit of wine; pure or highly rectified spirit (called also ethyl alcohol or ethanol, CH3.CH2.OH); the spirituous or intoxicating element of fermented or distilled liquors, or more loosely a liquid containing it in considerable quantity. It is extracted by simple distillation from various vegetable juices and infusions of a saccharine nature, which have undergone vinous fermentation.

Alcoholnoun

A class of compounds analogous to vinic alcohol in constitution. Chemically speaking, they are hydroxides of certain organic radicals; as, the radical ethyl forms common or ethyl alcohol (C2H5.OH); methyl forms methyl alcohol (CH3.OH) or wood spirit; amyl forms amyl alcohol (C5H11.OH) or fusel oil, etc.

Alcoholnoun

a liquor or brew containing alcohol as the active agent;

‘alcohol (or drink) ruined him’;

Alcoholnoun

any of a series of volatile hydroxyl compounds that are made from hydrocarbons by distillation

Alcoholnoun

a colourless volatile flammable liquid which is produced by the natural fermentation of sugars and is the intoxicating constituent of wine, beer, spirits, and other drinks, and is also used as an industrial solvent and as fuel

‘the use of petrol containing alcohol’; ‘it is an offence to drive if you have more than 80 mg of alcohol per 100 ml of blood’;

Alcoholnoun

drink containing alcohol

‘he has not taken alcohol in twenty-five years’;

Alcoholnoun

any organic compound whose molecule contains one or more hydroxyl groups attached to a carbon atom

‘unpleasant stuff like formaldehyde is produced as alcohols burn’; ‘polyvinyl alcohol’;

Alcohol

In chemistry, alcohol is an organic compound that carries at least one hydroxyl functional group (−OH) bound to a saturated carbon atom. 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 drinks.
