Alcohol, any of a class of organic compounds characterized by one or more hydroxyl (―OH) groups attached to a carbon atom of an alkyl group (hydrocarbon chain).
What is the structure of an alcohol?
One way of classifying alcohols is based on which carbon atom is bonded to the hydroxyl group. If this carbon is primary (1°, bonded to only one other carbon atom), the compound is a primary alcohol. A secondary alcohol has the hydroxyl group on a secondary (2°) carbon atom, which is bonded to two other carbon atoms.
What are the 4 types of alcohol?
The four types of alcohol are ethyl, denatured, isopropyl and rubbing. The one that we know and love the best is ethyl alcohol, also called ethanol or grain alcohol. It’s made by fermenting sugar and yeast, and is used in beer, wine, and liquor.
What is the general structural representation of an alcohol?
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.
What is the structural formula of a primary alcohol?
A primary (1°) alcohol is one in which the carbon atom (in red) with the OH group is attached to one other carbon atom (in blue). Its general formula is RCH2OH.
What is the chemical name for alcohol?
What are examples of alcohol?
The definition of alcohol is a liquor that contains ethanol and has the potential to intoxicate drinkers, and it can be burned as fuel. Whiskey, vodka, rum and gin are each an example of alcohol.
What type of alcohol is most popular?
Beer is the most popular alcoholic beverage worldwide. In fact, after water and tea, beer is the most commonly-consumed drink in the world.
What are 3 categories of alcohol?
Alcoholic drinks are divided into three general classes: beers, wines, and distilled beverages.

What is difference between alcohol and ethanol?
Often referred to simply as alcohol. Ethanol, also known as ethyl alcohol, drinking alcohol or grain alcohol, is a flammable, colorless, slightly toxic chemical compound, and is best known as the alcohol found in alcoholic beverages. Ethanol is a flammable, colorless, and slightly toxic chemical compound.
Is ethanol stronger than alcohol?
Sanitizer Alcohol Percentage
The World Health Organization suggests that 70% ethyl alcohol is superior to isopropyl alcohol against the influenza virus, however, both provide adequate germicidal properties. Ethanol is recommended at higher % concentration, usually 80%.
What is the functional group of alcohol?
Alcohol molecules all contain the hydroxyl (-OH) functional group. They are a homologous series and have the general formula C nH 2n+ 1OH.
How do we classify alcohol?
Alcohols may be classified as primary, secondary, or tertiary, according to which carbon of the alkyl group is bonded to the hydroxyl group. Most alcohols are colourless liquids or solids at room temperature.
Which one is present in an alcohol?
Alcohols are organic molecules assembled from carbon (C), oxygen (O), and hydrogen (H) atoms. When 2 carbons are present, the alcohol is called ethanol (also known as ethyl alcohol). Ethanol is the form of alcohol contained in beverages including beer, wine, and liquor.
What is difference between primary and secondary alcohol?
A primary alcohol is an alcohol in which the hydroxy group is bonded to a primary carbon atom. It can also be defined as a molecule containing a “–CH2OH” group. In contrast, a secondary alcohol has a formula “–CHROH” and a tertiary alcohol has a formula “–CR2OH”, where “R” indicates a carbon-containing group.
