In the thiocyanate ion, SCN– three resonating structure are possible with the electron-dot method as shown in figure :
The decreasing order of % contribution in resonance hybrid is:
A
y> x > z
B
y > z > x
C
z> x > y
D
Cannot predicted.
Answer
y> x > z
Explanation
Solution
(i) Negative charge should be at more electronegative atom.
(ii) Less formal charge provides more stability.
