In the reaction CH3−CH3|CH−CH2O−CH2−CH3+heatedHI→..........
Which of the following compounds will be formed?
CH3−CH3|CH−CH2OH+CH3−CH2−I
After the protonation, the nucleophile - Iominus - can attack either of the two carbons attached to the oxygen atom of the now-protonated oxonium ion. But SN2 like nucleophilic attack is much more feasible at the less-hindered carbon.
