Which alcohol is characterized by the chemical name 'ethyl'?

Beverage alcohol is characterized by the chemical name "ethyl," which is derived from ethanol (C2H5OH). Ethanol is the type of alcohol that is found in alcoholic beverages such as beer, wine, and spirits. It is this specific form of alcohol that is consumed recreationally and is regulated in terms of legal limits for driving under the influence.

Other types of alcohols mentioned in the question have entirely different chemical structures and uses. For instance, rubbing alcohol typically refers to isopropyl alcohol, which is used as a disinfectant and is not suitable for consumption. Industrial alcohol often refers to methanol or other forms that are not meant for human consumption and can be toxic. The term "activity alcohol" does not apply and seems to be misleading, as it is not a recognized category of alcohol in pharmacology or chemistry. Therefore, beverage alcohol stands out as the only type associated with the ethyl classification.
