NEET 2019 Odisha · ChemistryPrevious Year Question
The major products C and D formed in the following reaction respectively are:
Answer: (A) (A) and . \textbf{Answer:} (A) and \textbf{Solution:} This is a -butyl propyl ether.
- A.(A) and ✓
- B.(B) and
- C.(C) and
- D.(D) and
Correct Answer
(A) (A) and
Solution & Explanation
\textbf{Answer:} (A) and \textbf{Solution:} This is a -butyl propyl ether. On cleavage with HI the C–O bond breaks on the side that can form the more stable carbocation. The -butyl group leaves as a stable carbocation (), which is trapped by iodide to give -butyl iodide ; the propoxide part is first released as 1-propanol. With excess HI, the 1-propanol is further converted to 1-iodopropane . Hence the two iodides (C) and (D) are obtained.
