Vedclass · Answer

(C) When ethanol is heated in the presence of conc. $H_2SO_4$,dehydration takes place to give ethene.This process involves the removal of a water molecule from the ethanol molecule,which is why it is called a dehydration reaction.$\underset{	ext{Ethanol}}{C_2H_5OH}$ $\xrightarrow[160^{\circ}C - 170^{\circ}C]{	ext{Conc. } H_2SO_4} \underset{	ext{Ethene}}{CH_2=CH_2} + \underset{	ext{Water}}{H_2O}$
