The Chemical Composition of Isopropyl Alcohol

The chemical term, alcohol, is characterized as an organic compound whose molecule contains the elements Carbon (C), Hydrogen (H), and Oxygen (O).

Tright here are many type of various kinds of alcohol. However, you may be many acquainted via ethyl alcohol, which is offered in alcoholic bevereras.Rubbing alcohol, as it is sold this particular day, generally includes the compound isopropyl alcohol.
