Question
Identify X in the given reaction.
CH3CH2OH(aq)X→CH2=CH2(g)+H2O(l)
CH3CH2OH(aq)X→CH2=CH2(g)+H2O(l)
Answer: Option D
:
D
The given reaction is a dehydration reaction in which ethanol is when heated with concentrated sulphuric acid at 443 K givesethene and water.
In this reaction, conc.H2SO4 is used because it is a strong dehydrating agent. The reaction occurs as follows:
CH3CH2OH(aq)Hotconc.H2SO4−−−−−−−−−−→CH2=CH2(g)+H2O(l)
Therefore, X is concentrated sulphuric acid.
