Question

A compound 'x' on heating with excess conc. Sulphuric acid at 443 k gives an unsaturated compound 'y'. 'x' also react 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 is c2H5OH
y is ch2=ch2
z is hydrogen

sulphuric acid acts as a dehydrating agent

Answer 2

X - is ch3ch2oh ethanol
Y - ch2 double bond ch2 or ethene
Z - h2 gas
Reaction:
Ch3ch2oh + NA. Gives ch3ch2o na. + h2 gas
