formula of ethanol
H H
H-C-C-O-H
H H
when ethanol is heated in excess of H2SO4 at 443K , dehydration takes place AND
ETHANOL IS CONVERTED INTO ETHENE
therefore
443K
C2H5OH +H2SO4(EXCESS) ----------> C2H4 + H2O
thus in this reaction H2SO4 acts as dehydrating agent

The structural formula of ethanol is CH3CH2OH. When ethanol is heated with an excess of conc. Sulphuric acid at 443 K it gives ethane. Here conc. Sulphuric acid acts as a dehydrating agent. CH3CH2OH-CH2=CH2 + H2O

Ethanol -> CH₃CH₂OH

When Ethanol is heated with excess of conc. H₂SO₄, at 443 K , Ethene is formed .
                      conc. H₂SO₄
CH₃CH₂OH ----------------------> CH₂ = CH₂ + H₂O

H₂SO₄ acts as a dehydrating agent , that removes water molecule from et

Ethanol : CH3CH2OH

CH3-CH2OH in the presence of hot concentrated H2SO4 gives CH2=CH2+H2O

ETHANOL IS CONVERTED TO ETHENE
