Concept explainers
(a)
Interpretation: An acceptable Lewis structure from the given condensed structure is to be drawn such that all the atoms have a zero formal charge.
Concept introduction: The arrangement of valence electrons among the atoms present in a molecule is represented by the Lewis structure of that molecule. The electron pairs in the molecule are considered to be delocalized.
