Question

What is ethanol state its two properties what happens when it is heated with exces of conc hydrochloride acids at 433k write the structural formulaof the main product formed?

Answer 1

Ethanol is a carbon compound commonly called alcohol.

$properties \: of \: ethanol$

1) it's liquid at room temperature

2) ethanol is soluble in water

$reaction \: with \: excess \: concentrated \: sulphuric \: acid \:$

heating ethanol at 443k with excess concentrated sulphuric acid results in the dehydration of ethanol to give ethene a unsaturated hydrocarbon

see the picture....

Answer 2

Ethanol: Molecules in which hydroxy group attached to alkyl groups are the alcohols.

The formula of alochols can be written by replacing hydrogen ("H") from alkanes with hydroxy group ("OH").

Properties:

• Ethanol exists in liquid state at room temperature.

• Mixture of alcohol to ethane results in the formation of ethanol and it is the active ingredient of all alcoholic drinks. Even a small quantity of ethanol if consumed can causes drunkenness.

• Being a good solvent, it is also used in medicines like tincture of iodine, cough syrups, and many other tonics.

Reaction of ethanol with excess concentrated sulphuric acid acting as dehydrating agent at 443 K results in the dehydration of Ethanol leading to the formation of Ethene.

C2H5OH (Hot Conc. H₂SO₄)−−−−−−−−−−−−> C2H4+ H2O

Structural formula of compound formed:

CH2=CH2(ethene)
