CHEM 205 Worksheet (WS1)
46 Points Total
Key Topics: Lewis Structures, Formal Charge, Resonance, Hybridization, Functional Group Identity
1. On each line below, write the generic functional group being highlighted by each box. Do not name the
compound, just indicate the functional group being highlighted. (2pts each)
2. Identify the formal charge at each atom indicated by an arrow. Assume all hydrogens and lone pairs
that are present have been shown. (1pt each)
3. Draw a valid Lewis structure (bond-line structure also fine) having the molecular formula below. Be
sure to show the formal charge in your structure. If applicable, show lone electron pairs. (3pts)
4. Identify the hybridization state and geometry for each nitrogen atom in the structure below. It may
help to draw other resonance structures or draw the functional group out to determine each accurately.
(1pt each for correct hybridization and geometry)
