JEE Main Chemistry question
In the following two ether-cleavage reactions, what is the sum of moles of HI consumed? (i) An aliphatic (non-aromatic) cyclic methyl ether is treated with 2 moles of concentrated HI. (ii) Anisole (phenyl methyl ether) is treated with 1 mole of concentrated HI.
Answer: 3
Solution
In reaction (i), the aliphatic ether has no aromatic ring to protect either C–O bond, so both the methyl–O bond and the ring–O bond can be cleaved, consuming 2 moles of HI to give the alkyl iodide and methyl iodide. In reaction (ii), the
