SUMMARY

The discussion clarifies the concepts of formal charges and partial charges in organic chemistry. An atom with a formal charge of zero has no charge, regardless of the overall charge of the molecule or ion. Conversely, an atom with a non-zero formal charge possesses a complete charge, independent of the molecule's overall charge. Additionally, due to differences in electronegativity, an atom may exhibit a partial charge despite its formal charge status.

PREREQUISITES
  • Understanding of formal charge calculations in organic chemistry
  • Knowledge of electronegativity and its effects on molecular charge distribution
  • Familiarity with ion and molecule structures
  • Basic principles of polarity in chemical bonding
NEXT STEPS
  • Study formal charge calculation methods in organic molecules
  • Explore the concept of electronegativity and its impact on molecular interactions
  • Learn about the differences between complete and partial charges in chemical species
  • Investigate the role of polarity in determining molecular behavior
USEFUL FOR

Chemistry students, educators, and professionals seeking to deepen their understanding of charge concepts in organic chemistry.

I'm reading the fundamentals of organic chemistry these days and I'd like to make sure I get the following absolutely right:

1) If a certain atom in an ion or a molecule etc has a formal charge of zero then the atom itself has no charge on itself irrespective of whatever the charge might be overall on the ion or the molecule.

2) If a certain atom in an ion or a molecule etc has a non-zero formal charge then the atom itself has a charge (a complete charge not a partial charge) on itself irrespective of whatever the charge might be on the complete ion or the molecule or even if the complete ion or molecule etc is neutral.

3) However due to (differences of) polarity (irrespective of the formal charge), an atom in an ion or a molecule etc. may have a partial charge.

Am I correct on all of the above three points?

My bad. In the third point I meant to write electronegativity instead of polarity.
 
You are correct.
