Question

(1) How would you bring about following conversation ? Name the process and write the reaction involved (a)ethanol to ethene (b)ethanol to ethanoic acid.

Answer 1

Hey Friend,

1. Ethanol to Ethene -

*Process -

Dehydration - it involves elimination of elements of water from alcohol. 

*Reaction -

C2H5OH -----> C2H4 + H2O

*Catalyst -

concentrated H2SO4 at 170 degrees or Al2O3 at 350 degrees 

2. Ethanol to ethanoic acid

*Process -

Oxidation - the process of combining oxygen to alcohol to given carboxylic acid.

*Reaction -

C2H5OH + [O] ----> CH3CHO + H2O 
CH3CHO + [O] ----> CH3COOH + H2O

*Catalyst -

K2Cr2O7 (oxidizing agent) acidified with dilute H2SO4 at high pressure and low temperature

Hope it helps!

Answer 2

Hey there !!


Before writing its answer I would like to Give you clarification about

What processess are involved here


What is dehydration ?


Dehydration is that process by which water molecules are removed from a compound

For example -

CH₃ - CH₂OH ⟶ CH₂ =CH₂ + H₂O

( Ethanol ) ( Ethene ) ( Water )



Which is the conversation of ethanol to ethens
here in the presence of Con. H₂SO₄ , Ethanol is heated at 443K The water molecules get from ethanol and converted into ethene

Now let's know
What is oxidation reaction ?


Well oxidation Reaction is that reaction in which oxygen is added or Hydrogen is removed from it , You know what K₂Cr₂O₇ ( potassium dichromate ) or KMnO₄ ( Potassium permanganate ) Are present as oxidizing agents ?

well we can conclude now

CH₃ CH₂OH + [ O ] → CH₃COOH

( Ethanol ) ( Ethanoic acid )

-----------------------------------------------------------------


Now

A ) Ethanol to ethene

Conversation Process Name - Dehydration


B ) Ethanol to Ethanoic acid

Conversation Process Name - Oxidation Reaction



Hope this would help you !!
