Q38.Relative stability of the contributing structures is : (1) (I) > (II) > (III) (2) (I) > (III) > (II) (3) (II) > (I) > (III) (4) (III) > (II) > (I)
What This Question Tests
This question assesses the understanding of rules for determining the relative stability of contributing resonance structures, prioritizing structures with complete octets, less charge separation, and negative charge on more electronegative atoms.
