Question

a compound x on heating with excess cone. sulphuris acid at 443k gives an unsaturated compound y . also react with sodium metal to evilve a colourless gas z . identify x y z . write the equation of tue chemical reaction of formation of y and also write the role of sulphoric acid in the reaction

Answer 1

compound X = ethanol
Compound Y= ethene
gas z= hydrogen

sulphuric acid is use as dehydrating agent.

Answer 2

X is ethanol(C2H5OH)
Y is ethene(C2H4)
Z is hydrogen gas.
C2H5OH= C2H4+H20.
heat+hot conc.H2SO4
sulphuric acid act as adehydrating agent.
