MCQ
Compare relative stability of the following resonating structure.
- A$p > q > r$
- B$q > p > r$
- C$q > r > p$
- ✓$p > r > q$
✓
Answer
Correct option: D.
$p > r > q$
d
$(d)$ $(i)\, -ve$ charge on electronegative atom increases stability.
$(ii)$ $- C \equiv N$ system is more stable than $C = C = N$ system. So stability order is $p > r > q$
