Question

The product obtained when benzyl phenol ether is heated with HI in the mole ratio 1:1 are
1. Phenol 2. Benzyl alcohol
3. Benzyl iodide 4. Iodobenzene
A. 1 and 3 only
B. 3 and 4 only
C. 1 and 4 only
D. 2 and 4 only

Answer 1

Correct Answer - A
Ethers are readily attacked by HI to give alcohols or phenols and halides .
`underset("Benzylphenyl ether")(C_(6)H_(5)CH_(2)OC_(6)H_(5))to underset("Phenol")(C_(6)H_(5)OH) + underset("Benzyliodide")(C_(6)H_(5)CH_(2)I)`
However, when excess of HI is used , only iodide (alkyl or aryl ) is obtained as major product.
