Is Sugar an alcohol?

Sugar alcohols are neither sugars nor alcohols. They are carbohydrates with a chemical structure that partially resembles sugar and partially resembles alcohol, but they don't contain ethanol as alcoholic beverages do. Most sugar alcohols are less sweet than sucrose; maltitol and xylitol are about as sweet as sucrose.

What is the 3 types of alcohol?

Main Types of Alcohols
There are three types of alcohol. Alcohols are classified as primary, secondary or tertiary alcohols. The classification is done in accordance to where the carbon atom of an alkyl group is attached to the hydroxyl group.

How do you classify alcohols?

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.

How many types of monohydric alcohol are there?

Based on the total number of hydroxyl groups present, there are three types of alcohol. They are: Monohydric alcohols: These contain one -OH group. For example, CH3CH2-OH.

Is glycerol a trihydric alcohol?

Glycerol (GLIH-ser-ol) is a clear, colorless, odorless, sweet-tasting syrupy liquid. It is a trihydric alcohol, meaning that its molecules contain three hydroxyl (−OH) groups.

How is alcohol defined?


Medical Definition of Alcohol
Alcohol: An organic substance formed when a hydroxyl group is substituted for a hydrogen atom in a hydrocarbon. The type of alcohol used in alcoholic beverages, ethanol, derives from fermenting sugar with yeast. After alcohol is ingested, the body converts it to sugar-based fuel.

Is glycerol a primary or secondary alcohol?

Glycerol is a triol containing two primary alcohols (RCH2OH) and one secondary alcohol (R2CHOH) and its unambiguous IUPAC name is given as propane-1,2,3-triol.

What are primary and secondary alcohols?

A primary alcohol is an alcohol which has the hydroxyl group connected to a primary carbon atom. In contrast, a secondary alcohol has a formula “–CHROH” and a tertiary alcohol has a formula “–CR2OH”, where “R” indicates a carbon-containing group. Examples of primary alcohols include ethanol and butanol.

What is Trihydric alcohol?

n. An alcohol containing three hydroxyl groups, such as glycerol.
