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.

Answer 1

Answer

X - Ethanol: C2H5OH / Ethyl Alcohol

Y - Ethene: (C2H4)

Z - Hydrogen: (H2)

 

Role of sulphuric acid: dehydrating agent

Answer 2

Answer:

X is ethanol

Y is ethene

Z is hydrogen

Explanation:

Conc. H2So4 is a dehydrating agent and dehydrades water from ethanol to form ethene
