What is dihydric alcohol with example?
Dihydric alcohols: They contain two -OH groups. Example, 1,2-Ethandiol. Trihydric alcohols: They contain three -OH groups. Example 1,2,3-Propantriol.
How do you name a secondary alcohol?
A secondary (2°) alcohol is one in which the carbon atom (in red) with the OH group is attached to two other carbon atoms (in blue). Its general formula is R2CHOH.
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.
Is ether an alcohol?
Ethers are similar in structure to alcohols, and both ethers and alcohols are similar in structure to water. In an alcohol one hydrogen atom of a water molecule is replaced by an alkyl group, whereas in an ether both hydrogen atoms are replaced by alkyl or aryl groups.

How do you tell if a compound is an alcohol?
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 are the first 5 alcohols?
