Is an example of trihydric alcohol and is an example of dihydric alcohol?
Dihydric alcohols: These contain two -OH groups. For example, 1,2-Ethandiol. Trihydric alcohols: These have three -OH groups. For example 1,2,3-Propantriol.
What are monohydric dihydric and trihydric alcohol give their examples?
An alcohol that has one hydroxyl group is called monohydric; monohydric alcohols include methanol, ethanol, and isopropanol. … Glycols have two hydroxyl groups in their molecules and so are dihydric. Glycerol, with three hydroxyl groups, is trihydric.
What is dihydric and trihydric alcohol?
Dihydric alcohols: They contain two -OH groups. Example, 1,2-Ethandiol. Trihydric alcohols: They contain three -OH groups.
Is glycerol a dihydric alcohol?
Glycerol is a trihydric alcohol because it contains three hydroxyl or alcohol groups. Glycerin is a thick liquid with a sweet taste that is found in fats and oils and is the primary triglyceride found in coconut and olive oil.
Is resorcinol a dihydric alcohol?
Explanation: Resorcinol is dihydric alcohol, in which hydroxyl group is attached at 1, 3 positions to each other in benzene ring.
Is ethylene glycol a dihydric alcohol?
Ethylene glycol (EG) is a multidirectional, dihydric alcohol, which is widely used in food, chemical and automotive industries. EG is a compound of similar toxicity to ethanol (EA).
What are phenols give an example?
Therefore, trivial names (i.e., vanillin, salicylic acid, pyrocatechol, resorcinol, cresol, hydroquinone, and eugenol) are often used for the most common phenolic compounds. … For example, the systematic name for vanillin is 4-hydroxy-3-methoxybenzaldehyde.
What is dihydric phenol?
When benzene ring has 2 -OH groups, it is called Dihydric phenol.
What are monohydric alcohols give an example?
Examples of monohydric alcohols are methyl alcohol, ethyl alcohol, propyl alcohol, and isopropyl alcohol. (See also Polyhydric Alcohol.)
What is the name of dihydric alcohol?
Example of dihydric alcohol is catechol which contains two hydroxyl groups attached to the two carbon atoms of the benzene ring. The other important example of dihydric alcohol is ethylene glycol. It is a vicinal diol which means that the two hydroxyl groups are attached to the carbon atom adjacent to each other.
What is the general name of dihydric alcohol?

What is a trihydric alcohol?
[ trī-hī′drĭk ] n. An alcohol containing three hydroxyl groups, such as glycerol.
Is catechol a dihydric phenol?
Advances during the past one and a half decade in the chemistry of dihydric phenols are reviewed in this chapter concerning 1,2-dihydroxybenzenes (catechols), 1,3-dihydroxybenzenes (resorcinols), and 1,4-dihydroxybenzenes (hydroquinones).
What are monohydric alcohol and how are they classified?
Alcohols having only one hydroxyl group in their molecules are called monohydric alcohols. Monohydric alcohols are classified according to the type of hybridization of th carbon atom to which the hydroxyl group is attached .
