How are alcohols made
WebFatty alcohols (or long-chain alcohols) are usually high-molecular-weight, straight-chain primary alcohols, but can also range from as few as 4–6 carbons to as many as 22–26, … WebSugar alcohols are added to foods because of their lower caloric content than sugars; however, they are also, in general, less sweet, and are often combined with high-intensity sweeteners. They are also added to chewing gum because they are not broken down by bacteria in the mouth or metabolized to acids, and thus do not contribute to tooth decay .

WebAlcohols fall into different classes depending on how the -OH group is positioned on the chain of carbon atoms. There are some chemical differences between the various types. Primary alcohols. In a primary (1°) alcohol, the carbon atom that carries the -OH group is only attached to one alkyl group. WebAlcohols are the compounds of the general formula R – OH, where R is an alkyl or a substituted alkyl group. Thus, alcohols are the derivatives of alkanes in which one or more H atoms are replaced by -OH. Alcohols are very important industrial chemicals. Ethanol is widely used as an antiseptic in the form of a rectified spirit.
