Vedclass · Answer

(A) The dehydration of alcohols in the presence of a concentrated acid catalyst like $H_2SO_4$ at high temperatures $(160-170 \ ^oC)$ results in the formation of an alkene with the same number of carbon atoms.Specifically,the dehydration of ethanol $(C_2H_5OH)$ proceeds as follows:$CH_3CH_2OH \xrightarrow{conc. H_2SO_4, 160-170 \ ^oC} CH_2=CH_2 + H_2O$Thus,ethylene $(CH_2=CH_2)$ is obtained from ethanol $(C_2H_5OH)$.

Ethylene may be obtained by dehydration of which of the following with concentrated $H_2SO_4$ at $160-170 \ ^oC$?
