(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.

Point out the problems in cases where structure is invalid. CH3 CH;-N-CH-CH3 ČH3 A. This structure is correct because the valance of Nitrogen is complete. B. This is not a correct Lewis structure because Nitrogen can accommodate more atoms. C. This is not a correct Lewis structure because Nitrogen has a charge if it does not have three bonds. D.
