Vedclass · Answer

(A) The reaction of ethanol with concentrated $H_2SO_4$ at $413 \ K$ is an example of intermolecular dehydration of alcohols to form ethers.This reaction proceeds via an $S_N2$ mechanism.In the first step, the alcohol is protonated by the acid.In the second step, a second molecule of ethanol acts as a nucleophile and attacks the protonated alcohol, displacing a water molecule to form diethyl ether.Since the rate-determining step involves the collision of two molecules, it is a bimolecular nucleophilic substitution reaction $(S_N2)$.

$Ethanol \xrightarrow{H_2SO_4, 413 K} \text{diethyl ether}$. The above reaction is which type?
