- B V \(\gt\) II \(\gt\) IV \(\gt\) III \(\gt\) I
- C \(\mathrm{V}\gt\mathrm{II}\gt\mathrm{III}\gt\mathrm{I}\gt\mathrm{IV}\)
- D II \(\gt\) III \(\gt\) IV \(\gt\) V \(\gt\) I
Answer & Solution
Correct Answer
(A) \(\mathrm{I}\gt\mathrm{III}\gt\mathrm{IV}\gt\mathrm{II}\gt\mathrm{V}\)
Step-by-step Solution
Detailed explanation
Benzylic carbocation \(\left(\mathrm{C}_6 \mathrm{H}_5-\stackrel{+}{\mathrm{C}} \mathrm{H}_2\right)\) is more stable due to \((+\mathrm{M})\) effect of \(\mathrm{C}_6 \mathrm{H}_5\) then \(3^{\circ}\) is more stable due to three methyle group then \(1^{\circ}\) carbocation. In…
