Question

A compound 'X' on heating with excess conc. Sulphuric acid at 443 K gives an unsaturated compound 'Y'. 'X' also texted with sodium metal to evolve a colourless gas 'Z'. Identify 'X','Y','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

Y --------->Ethene

Z -----------> Hydrogen gas.

Equation for formation of Y

$CH _{3}CH _{2}OH------ \frac{hot \: conc.}{ \:: H _{2}SO _{4} \: }---->CH _{2} = CH _{2} + </p><p>H _{2} O$

Here Sulphuric acid acts as dehydrating agent.

Answer 2

Answer:

X is ethanol

Y is ethene

Z is hydrogen gas
