Chemistry, asked by shrinidhialur21, 1 year ago

A compound 'X' on heating with excess concentrated 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

BadaSaGadha: it was such a hard question today :(

BadaSaGadha: I lost 2 marks

anuritha: Don't worry friend ,if all student feel it difficult ,that would give grace marks and each sub questions marks only 1/2 ...so don't worry

shrinidhialur21: okkkk but some intligent people write it ......

BadaSaGadha: yes of course

According to the question,
X - ethanol
Y-Ethene
Z-hydrogen gas

The equations are :
1) C2H5OH - - - - - >C2H4 + H2O
2) C2H5OH +Na - - - - - >C2H5ONa +H2

Sulphuric acid acts as a dehydrating agent in the reaction.....

BadaSaGadha: role of sulphuric acid ?

Hasti152002: thx for correction

BadaSaGadha: alright

Answered by anuritha

When alcohol (X), is catalysed by hot concentrated sulfuric acid, it produces ethene(Y)... This process is used for denaturing alcohol for unfit for drinking

When ethene is reacted with sodium produces colourless hydrogen gas (Z)

The use of sulphuric acid is to speed up the reaction or dehydrating agent a and make alcohol from unfit of drinking

anuritha: Pls mark it as brainiest answer

hsag1025: The way u answered , u will get full marks sis

anuritha: thanku
