Dear User!

☯ Question: ☯

A compound 'X' on heating with excess conc. sulphuric acid at 443 K gives an unsaturated compound 'Y', 'X' also reacts with sodium metal to 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 sulphuric acid in the reaction.

☯ Answer : ☯

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%)

Answer 2

Answer:

Concentrated sulphuric acid acts as a dehydrating agent in this reaction and removes a molecule of water.

Note: When Ethanol (x) reacts with sodium colorless Hydrogen gas (z) is evolved.

CH3CH2OH + Na--- C2H5ONa + H2

a) Ethanol

b) Ethene

c) H2
