Question

A compound 'X' on heating with excess of conc . sulphuric acid at 442K gives an unsaturated compound Y . X also reacts with sodium metal ot evolve a colourless gas Z . identify X,Y and Z . write the equation of the chemical reaction of formation of Y and also write the role of sulpahuric acid in the reaction . ​

Answer 1

When Ethanol is heated with concentrated Sulphuric acid, Ethene is collected over water. This Process is also known as ,"Dehydration of Ethanol".

Reaction with Ethanol :

$\huge{ \mathsf{C{ \tiny2}H{ \tiny5}OH}} - { \tiny{ \underline{ ^{conc.H2SO4}}}} \: { \mathsf{ \huge{CH{ \tiny2} - CH{ \tiny{2}}}}} \: +{ \huge{ \mathsf{ H{ \tiny2}0}}}$

Thus, In this Question, It is given that A compound 'X' on heating with excess concentrated h2so4 acid at 443k gives an unsaturated compound y. X also reacts with na metal to evolve a colorless gas z .

Required Compound X is (Ethanol) or C2H50H

Required Unsaturated Compound Y is Ethene or C2H4

Required Colourless Gas Z is H2 ( Hydrogen gas)

Things To Remember !

⏪ Ethanol is insoluble in water and while all organic Compound insoluble in water!

⏪ Ethanol is used as fuel along with Petrol . Generally it is used in cars.

⏪ Ethanol is used as Drinking (Wine), it's Contains Whiskey (35%), Beer ( 10% to 20%) and Wine (6%)
