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 $p > r > q$
