Question

A compound 'X' on heating with excess conc. 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.

PLEASE ANSWER WITH EXPLANATION​

Answer 1

Answer:

X is ethanol

Y is ethene

Z is hydrogen

Explanation:

C2H5OH on heating with excess sulphuric acid gives CH2=CH2 and H2O

Role if sulphuric acid is dehydrating agent.

Ethanol reacts with sodium metal to evolve hydrogen gas which is a colourless gas
