Increasing order of stability of the resonance structures is:
Choose the correct answer from the options given below:
Choose the correct answer from the options given below:
- $D , C , A , B$
- C, D, A, B
- D, C, B, A
- $C, D , A , B$
The Correct Option is B
Solution and Explanation
1. Factors affecting resonance stability: Structures with complete octets are more stable. Negative charges on more electronegative atoms are favored. Separation of charges decreases stability.
2. Analysis of the given structures: Structure C has significant charge separation and is the least stable. Structure D has localized charges but disrupts the aromatic system, so it is less stable than A and B. Structure A is more stable than C and D because it retains partial resonance. Structure B is the most stable because it has complete resonance and no significant charge separation.
Thus, the correct order of stability is: \[ \text{C} < \text{D} < \text{A} < \text{B}. \]

Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
