Question

state the physical properties of ethyl alcohol

Answer 1

Properties of ethyl alcohol:

1. Ethanol's chemical formula is C2H5OH.

2.  Pure ethanol is a flammable, colorless liquid with a boiling point of 78.5° C.

3.  Its low melting point of -114.5° C allows it to be used in antifreeze products.

4.  It has a pleasant odor reminiscent of whiskey.

5.  Its density is 789 g/l about 20% less than that of water.

Answer 2

The chemical compound ethanol, also known as ethyl alcohol or grain alcohol, is the bio-alcohol found in alcoholic beverages. When non-chemists refer to "alcohol", they almost always mean ethanol. It is also increasingly being used as a fuel (usually replacing or complementing gasoline). Ethanol's chemical formula is C2H5OH.
Properties

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. It is easily soluble in water and is itself a good solvent, used in perfumes, paints and tinctures. Alcoholic drinks have a large variety of tastes, since various flavor compounds are dissolved during brewing. >A solution of 70-85% of ethanol is commonly used as a disinfectant; it kills organisms by denaturing their proteins and dissolving their lipids: it is effective against most bacteria and fungi, and many viruses, but is ineffective against bacterial spores. This disinfectant property of ethanol is the reason that alcoholic beverages can be stored for a long time.

Ethanol can lose a proton from the hydroxyl group and is a very weak acid, weaker than water. The CAS number of ethanol is 64-17-5 and its UN number is UN 1170.
