Step 1:I'll solve this chemistry problem step by step, focusing on drawing the correct Lewis structure for hydrogen peroxide (H₂O₂).
Step 2:: Determine the total number of valence electrons
- Total valence electrons: $$2 + 12 = 14$$ electrons
- Hydrogen (H): 1 electron × 2 atoms = 2 electrons - Oxygen (O): 6 electrons × 2 atoms = 12 electrons
Step 3:: Arrange atoms and connect with single bonds
- Initial structure uses $$4$$ electrons (single bonds)
- Place oxygen atoms next to each other - Connect each oxygen to a hydrogen atom
Step 4:: Distribute remaining electrons
- Each oxygen receives $$3$$ lone pair electron groups
- Add lone pairs to oxygen atoms to complete their octet
Step 5:: Final Lewis structure
- Each oxygen has $$3$$ lone pairs
- Oxygen-oxygen single bond - Each hydrogen attached to an oxygen with a single bond
Final Answer
\text{H-O-O-H structure with 3 lone pairs on each oxygen} This Lewis structure represents the correct arrangement for hydrogen peroxide, showing single O-O and O-H bonds with complete octets for oxygen atoms.
