MCQ
Ether is obtained from ethyl alcohol in presence of $\ce{H_2SO_4}$ at?
- A$113K$
- B$443K$
- ✓$413K$
- D$213K$
✓
Answer
Correct option: C.
$413K$
Acid$-$catalyzed method of preparing symmetrical ethers from primary alcohols is temperature dependence. At $110^\circ 413KC$ or $383K$ to $130∘C$ or $403K,$ a $\ce{SN^2}$ reaction of the alcohol conjugate acid leads to an ether product. At higher temperatures $($over $150^\circ C$ or $423K)$ an $E_2$ elimination takes place and instead of ether, an alkene is obtained.
Thus, Ether is obtained from ethyl alcohol in presence of $\ce{H_2SO_4}$ at $413K.$
Thus, Ether is obtained from ethyl alcohol in presence of $\ce{H_2SO_4}$ at $413K.$
