chemical property and physical property of Etahnal.
Answers
Answer:
ethanol means ethyl alchohol
Explanation:
chemical formulae is c5h3oh
Explanation:
Ethanol's chemical formula is C2H5OH. Pure ethanol is a flammable, colorless liquid with a boiling point of 78.5° C. Its low melting point of -114.5° C allows it to be used in antifreeze products. It has a pleasant odor reminiscent of whiskey. Its density is 789 g/l about 20% less than that of water.
Physical Properties
It is a colourless, volatile liquid with characteristic pleasant odour.
It has boiling point of 351 K.
Chemical Properties
Following are the important chemical properties of ethanol.
1. Combustibility
Ethanol can easily burn in air to produce carbon dioxide and water.

3. Dehydration of Ethanol
When ethanol is heated to 1600-1700C in the presence of sulphuric acid (H2SO4) then a molecule of water is liberated and ethene is formed.

4. Oxidation of Ethanol
The oxidation of alcohol involves the formation of a carbon-oxygen bond. These reactions are also called degradation reactions because these reactions involve loss of hydrogen from ethanol. The oxidation process can be carried out by a number of reagents such as potassium permanganate (KMnO4) or chromic anhydride (CrO3).
1) Oxidation by Chromic Anhydride
By chromic anhydride ethanol is converted into ethanal.
