Vedclass · Answer

(B) When excess ethanol $(C_2H_5OH)$ is heated with concentrated sulphuric acid $(H_2SO_4)$ at $413 \ K$ $(140^{\circ}C)$,intermolecular dehydration occurs to form Diethyl ether $(C_2H_5-O-C_2H_5)$.$2C_2H_5OH \xrightarrow{conc. H_2SO_4, 413 K} C_2H_5-O-C_2H_5 + H_2O$Conversely,when ethanol is heated with excess concentrated sulphuric acid at a higher temperature of $443 \ K$ $(170^{\circ}C)$,intramolecular dehydration occurs to form Ethene $(C_2H_4)$.$C_2H_5OH \xrightarrow{conc. H_2SO_4, 443 K} C_2H_4 + H_2O$
