What type of reaction is the following: CH₃CH₂OH + H₂SO₄ (conc.) → CH₂=CH₂ + H₂O
Correct: C
In this reaction, ethanol (CH₃CH₂OH) is heated with concentrated sulfuric acid (H₂SO₄), resulting in the formation of ethene (CH₂=CH₂) and water. This is an elimination reaction, specifically a dehydration reaction, as water is removed from the ethanol molecule to form the alkene.
