(c) Al beruni
(d) Jaber bin hayyan
Answers
Explanation:
Ethanol was first prepared synthetically in 1826, through the independent efforts of Henry Hennel in Great Britain and S.G. Sérullas in France. Michael Faraday prepared ethanol by the acid-catalysed hydration of ethylene in 1828, in a process similar to that used for industrial ethanol synthesis today.
Systematic name: Ethanol
Other names: Ethyl alcohol, grain alcohol, hydroxyethane, EtOH
Other compounds: Acetaldehyde, Acetic acid
It can be prepared by the fermentation of sugar (e.g., from molasses), which requires an enzyme catalyst that is present in yeast; or it can be prepared by the fermentation of starch (e.g., from corn, rice, rye, or potatoes), which requires, in addition to the yeast enzyme, an enzyme present in an extract of malt.
Ethyl alcohol was prepared by Jabir bin hayyan.
Explanation:
- In western history, Jabir is best known for his contributions to chemistry.
- He emphasized systematic experimentation and contributed significantly to the de superstitionization of alchemy and its transformation into a science.
- He is credited with the invention of many types of now-standard chemical laboratory equipment, as well as the discovery and description of many now-standard chemical substances and processes such as hydrochloric and nitric acids, distillation, and cry stylization that have become the foundation of modern chemistry and chemical engineering.
