Drawing Lewis structure and structural formula

Click For Summary
SUMMARY

The discussion focuses on drawing the Lewis structure and structural formula for HCN and SO3 2-. The participant confirmed the accuracy of their Lewis structure for HCN. For SO3 2-, feedback was provided to include lone pairs on each oxygen atom and to indicate the formal charges on the atoms. The concept of formal charge was emphasized as essential for accurately representing the structure.

PREREQUISITES
  • Understanding of Lewis structures
  • Knowledge of formal charge calculation
  • Familiarity with molecular geometry
  • Basic chemistry concepts related to bonding and lone pairs
NEXT STEPS
  • Study the principles of drawing Lewis structures for polyatomic ions
  • Learn about formal charge and its significance in molecular structures
  • Explore molecular geometry and its relation to Lewis structures
  • Review examples of common polyatomic ions and their structures
USEFUL FOR

Chemistry students, educators, and anyone interested in mastering molecular structure representation and formal charge calculations.

(a) looks good.

The dot diagram for (b) looks good, but on the stick formula, I would suggest indicating the lone pairs present on each oxygen atom as well as indicating which atoms in the structure carry the negative charges (see the concept of formal charge to see how this is done).

Will do. I know how to apply formal charges, I just never thought it was necessary thanks though.
