Give the major products that are formed by heating each of the following ethers with HI
(i) `CH_(3)-CH_(2)-overset(CH_(3))overset(|)CH-CH_(2)-O-CH_(2)-CH_(3) " "` (ii) `CH_(3)-CH_(2)-CH_(2)-O-underset(CH_(3))underset(|)overset(CH_(3))overset(|)C-CH_(2)-CH_(3)`
(iii)

Text Solution

Verified by Experts

(i) `I^(-)` attacks at the smaller alkyl groups of the protonated ether

(ii) Cleavage of protonated ether occurs in such a way that a more stable carbocation is produced.

(iii) Nucleophilic attack occurs at the less electronegative `sp^(3)`-carbon rather than at the more electronegative `sp^(2)`-carbon.
