Question:
Methoxy ethane on reaction with hot concentrated HI gives
Methoxy ethane on reaction with hot concentrated HI gives
Show Hint
When ethers react with concentrated HI, they undergo cleavage to form alkyl iodides. In this case, methoxy ethane gives iodomethane and iodoethane.
Updated On: Jan 30, 2026
- iodomethane and ethanol
- iodomethane and iodoethane
- methanol and ethanol
- methanol and iodoethane
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Reaction.
Methoxy ethane (C\(_2\)H\(_5\)OCH\(_3\)) reacts with hot concentrated HI (hydriodic acid) to give iodides. In this reaction, the ether bond is cleaved to form iodomethane (CH\(_3\)I) and iodoethane (C\(_2\)H\(_5\)I).
Step 2: Analyzing the options.
(A) iodomethane and ethanol: Incorrect. Ethanol is not formed in this reaction.
(B) iodomethane and iodoethane: Correct. The reaction produces iodomethane and iodoethane.
(C) methanol and ethanol: Incorrect. Methanol and ethanol are not formed in this reaction.
(D) methanol and iodoethane: Incorrect. Methanol is not part of the product.
Step 3: Conclusion.
The correct products of the reaction are iodomethane and iodoethane, which corresponds to option (B).
