The major products C and D formed in the following reaction respectively are \( \text{H}_3\text{C}-\text{CH}_2-\text{CH}_2-\text{O}-\text{C}(\text{CH}_3)_3 \xrightarrow[\Delta]{\text{excess HI}} \text{C} + \text{D} \)

  1. \( \text{H}_3\text{C}-\text{CH}_2-\text{CH}_2-\text{OH} \text{ and } \text{OH}-\text{C}(\text{CH}_3)_3 \)
  2. \( \text{H}_3\text{C}-\text{CH}_2-\text{CH}_2-\text{I} \text{ and } \text{I}-\text{C}(\text{CH}_3)_3 \)
  3. \( \text{H}_3\text{C}-\text{CH}_2-\text{CH}_2-\text{OH} \text{ and } \text{I}-\text{C}(\text{CH}_3)_3 \)
  4. \( \text{H}_3\text{C}-\text{CH}_2-\text{CH}_2-\text{I} \text{ and } \text{HO}-\text{C}(\text{CH}_3)_3 \)

Correct answer · Option 2

\( \text{H}_3\text{C}-\text{CH}_2-\text{CH}_2-\text{I} \text{ and } \text{I}-\text{C}(\text{CH}_3)_3 \)

Explanation

Reaction of mixed ether with excess HI proceeds via an \( \text{S}_\text{N}1 \) mechanism for tertiary alkyl groups to form tert-butyl iodide and \( \text{S}_\text{N}2 \) for primary alkyl groups to form 1-iodopropane.
