Concept explainers
(a)
Interpretation:
Whether the given set are considered as valid pairs of contributing structures or not.
Concept Introduction:
Resonance is the method which explains electron’s delocalization in the molecules. It contrasts and compares more than two Lewis strictures which can signify the specific molecule. When a single molecule couldn’t explain the proper bonding between the two atoms so for explaining the proper bonding between two atoms resonance structure is used in place of Lewis structure.
(b)
Interpretation:
Whether the given set are considered as valid pairs of contributing structures or not.
