Chapter 1, Problem 47EQ
Interpretation Introduction
Interpretation:
The formal charge on the N and C atoms in the given molecule 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.
