Is an alcohol which contains 100 percent ethanol is fit to drink?

No, an alcohol which contains 100% ethanol is not fit to drink. Here's why:

* Toxicity: Pure ethanol is extremely concentrated and can be highly toxic. Consuming it can lead to severe health consequences, including:

* Severe dehydration: Ethanol is a diuretic, meaning it increases urination and can lead to severe dehydration.

* Organ damage: High concentrations of ethanol can damage the liver, kidneys, and other organs.

* Central nervous system depression: Ethanol can depress the central nervous system, leading to coma, respiratory failure, and even death.

* Unpleasant taste and smell: Pure ethanol has a harsh, burning taste and a strong, unpleasant odor. This makes it very difficult to consume.

* Lack of other components: Alcoholic beverages typically contain other components besides ethanol, such as water, sugars, and flavorings. These components contribute to the taste and palatability of the beverage.

In short, drinking 100% ethanol is extremely dangerous and should never be done.
