Answer

Structure 1 is minor, and structure 2 is major.

b. Both structures 1 and 2 are equal contributors

Step by step solution

Step-by-Step Solution Step 1: Major and minor contributors

The major contributor is the structure that has low energy and high stability. Its octet configuration is full. The minor contributor is the structure that possesses high energy and low stability.

Stability of resonance structures

The stability of resonating structuredirectly depends on the count of bonds in the Lewis structure More is the count of bonds; higher is the resonance structures鈥� stability. The structure contributes more to resonance if its stability is high.

Determination of contribution to resonance

a. Structure 2 contains an extra bond as compared to structure 1. So, the bond count in 2 is higher. Thus, structure 2 is the major contributor, whereas structure 1 is the minor contributor.

The major and minor contributors of a

b. Structures 1 and 2 possess identical factors for contribution by having equal bond count and charges. So, both the structures are equal contributors to resonance.
