Answer : X => ethanol
Y => ethene
Z => Hydrogen gas
Explanation :-when Ethanol is heated
with excess amount of concentrated
sulphuric acid, gives unsaturated
compound Ethene (C2H4)
here, conc. sulphuric acid as as
dehydrating agent because it ejects
water from ethanol.
reaction is---
CH3CH20H----> CH2= CH2 + H20l in
the presence of Conc. H2S04 at 443 K)
now, when Ethanol react with sodium,
colorless gas e. g., Hydrogen gas
evolved in reaction.
reaction is---
2CH3CH20H + Na--> C2H50Na + H2
Y => ethene
Z => Hydrogen gas
