Question

Main products formed during a reaction of 1-methoxy naphthalene with hydroiodic acid are :

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Ethers can be reactive under ​drastic reaction conditions (high temperature, high concentration) due to the cleavage of the C-O bond.​
In first step of the reaction, protonation of ether $\left(O\right)$ group take place.
In second step, $S_{N}2$ reaction take place, where $I^{-}$ nucleophile will attack the less hindered site to form methyl iodide and naphthol.


Hence, option (c) is correct.
