Chemistry Question on Resonance
Relative stability of the contributing structures is :
A
(I)>(III)>(II)
B
(I)>(II)>(III)
C
(II)>(I)>(III)
D
(III)>(II)>(I)
Answer
(I)>(II)>(III)
Explanation
Solution
Explanation:
1. Neutral structures are more stable than charged ones. Therefore, structure (I) is the most stable as it is neutral.
2. Among the charged structures, a positive charge (+) on a less electronegative atom (like carbon) is more stable than a positive charge on a more electronegative atom (like oxygen).
- Hence, structure (II), where C+ is present, is more stable than (III), where O+ is present.
**Order: **I>II>III.
Final Answer: Option (2).
