Question
Chapter 1, Problem 36EQ
Interpretation Introduction
Interpretation:
The total number of valance electrons in the given structure is to be counted and the formal charge on carbonyl carbon is to be calculated.
Concept Introduction:
Some organic
To calculate the formal charge on an atom in any given structure it is necessary to distinguish between the electrons that make up an atom’s octet and the electrons that formally “belong” to an atom. In any given Lewis structure all electrons associated with an atom either as an unshared pair or shared pair are part of that atom’s octet.
