Question
Chapter 2, Problem 8CTQ
Interpretation Introduction
Interpretation : Whether both structures of carbon dioxide in Model 2 are legitimate structures or not should be discussed.
Concept Introduction : A legitimate Lewis structure is an electron dot and line bond representation in which the total number of valence electrons is indicated. The number of valence electrons around hydrogen is two. The number of valence electrons around carbon, nitrogen, oxygen, fluorine atom is eight. This is called the octet rule.
