Select the ether among following that yields methanol as one the products on reaction with cold hydroiodic acid
According Zeise! method, when an ether reacts with cold HI, alkyl iodide and alcohol are formed. In case of asymmetrical ether, the alkyl halide is always formed from the smaller alkyl group provided no tertiary (3°) alkyl group is present and if any 3° alkyl group is present, the halogen gets attached with it. In case of alkyl aryl ethers, the products are always phenol and an alkyl halide.
