WebExplanation: In the presence of protic acids (sulphuric acid), alcohols undergo dehydration to produce alkenes and ethers under different conditions. For example: in the presence of sulphuric acid, dehydration of ethanol at 443 K yields ethene whereas it yields ethoxyethane at 413 K. This is an ideal method of preparation through primary alcohols. durmazlar sbt guillotine shears 2 pieceWebSynthesis of Diethyl Ether – (C 2 H 5) 2 O Ether is synthesised by the dehydration of ethanol using sulphuric acid.
