MCQ
Ether is obtained from ethyl alcohol in presence of H2SO4 at?
- A113K
- B443K
- C413K
- D213K
✓
Answer
- 413K
Explanaition:
Acid-catalyzed method of preparing symmetrical ethers from primary alcohols is temperature dependence. At 110°413KC or 383K to 130∘C or 403K, a SN2 reaction of the alcohol conjugate acid leads to an ether product. At higher temperatures (over 150°C or 423K) an E2 elimination takes place and instead of ether, an alkene is obtained.
Thus, Ether is obtained from ethyl alcohol in presence of H2SO4 at 413K.
