NEET levelSingle correct optionDifficulty 1 of 3ap022

Ethanol heated with excess conc. $H X_{2} SO X_{4}$ at 443 K mainly gives

Adiethyl ether
Bethanal
Cethene
Dethane

Answer: C

At 443 K with excess acid, ethanol undergoes dehydration (elimination) to ethene. At 413 K with excess alcohol, diethyl ether forms instead.
