Question

Equimolar quantities of ethanol and methanol are heated with conc. $H_{2}S{O}_4$ at $413K$. The product(s) formed is/are:

• A. $C_2{H}_{5}O{C}_2{H}_5$
• B. $C{H}_{3}OC{H}_3$
• C. $C_2{H}_{5}OC{H}_3$
• D. $C{H}_{3}C{H}_{2}C{H}_3$

Answer 1

Answer: (A), (B), (C)

$C_2{H}_{5}OC{H}_3$

Dehydration of alcohols is useful only for the preparation for symmetrical ethers.​ If dehydration of alcohol takes place at 413 K, then ether will be formed. The mechanism of dehydration of alcohol involves 3 steps.​
(i) Protonation of alcohol​
(ii) Nucleophilic attack​
(iii) Deprotonation of ether​

Hence, the correct answer will be option (a),(b) and (c).
