Question

A compound "X" on heating with excess conc. sulphuric acid at 443K 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 1

X - ethanol(CH3CH2OH)
Y - ethene (CH2=CH2)➡️unsaturated
Z - hydrogen gas➡️colourless

conc h2so4
CH3CH2OH----------------》
(X)
CH2=CH2 + H20
(Y)

sulphuric acid acts as a DEHYDRATING AGENT in the above reaction.
