In the IUPAC system, alcohols are named by changing the ending of the parent alkane name to -ol. Alcohols are classified according to the number of carbon atoms attached to the carbon atom that is attached to the OH group.
Which name represents an alcohol?

How do you identify alcohols?
Alcohols are organic molecules containing a hydroxyl functional group connected to an alkyl or aryl group (ROH). If the hydroxyl carbon only has a single R group, it is known as primary alcohol. If it has two R groups, it is a secondary alcohol, and if it has three R groups, it is a tertiary alcohol.
What is the suffix of alcohol?
The suffix –ol is used in organic chemistry principally to form names of organic compounds containing the hydroxyl (–OH) group, mainly alcohols (also phenol). The suffix was extracted from the word alcohol.
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 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.
Which alcohol is most easily dehydrated?
Which one of the following alcohols undergoes dehydration most easily? The reactivity order for dehydration of alcohols is tertiary alcohol > secondary alcohol > primary alcohol. Therefore, the alcohol, CH3 |CH3CH2-C-CH2CH3 | OH is dehydrated most rapidly.
What are the 3 types of alcohol?
There are three main types of alcohol: methyl, isopropyl, and ethyl which are also known as primary, secondary and tertiary alcohols respectively. All are toxic. Human beings can consume the only ethyl, or grain, alcohol, but the others find use as sterilizing agents, or as fuels.
Which alcohol is used in Whisky?
Whiskey. Whiskey is type of distilled alcoholic beverage, generally made from fermented grain mash including barley, corn, rye, and wheat. The distinctive taste of the drink is achieved after it is fermented in charred white oak wood. The aging process of whiskey stops once it is bottled from the casks.
When naming an alcohol the root is based on?
The root name is based on the longest chain with the -OH attached. The chain is numbered so as to give the alcohol unit the lowest possible number. The alcohol suffix is appended after the hydrocarbon suffix minus the “e” : e.g.
Is alcohol a base or acid?
With a pKa of around 16–19, they are, in general, slightly weaker acids than water. With strong bases such as sodium hydride or sodium they form salts called alkoxides, with the general formula RO− M+. The acidity of alcohols is strongly affected by solvation. In the gas phase, alcohols are more acidic than in water.
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.
What are alcohol used for?
Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry.
What are the first 5 alcohols?
The four most common alcohols, which are also the simplest, are methanol (CH3OH), ethanol(C2H5OH), propanol (C3H7OH) and butanol (C4H9OH).
