Module
Four: Part B Dot Structures of Molecules 30 points
Using
a periodic chart draw the electron dot structures of the following molecules:
(Choose One for each
question or the one circled on the paper)
1. NH3 CH4 H2O2 H2O 2. H2SO4 H3PO4 HClO4 HClO3
3. HNO3 H2CO3 HNO2 4. CO2 HCN
CO SO3
5. HC2H3O2 H2C2O4 HCHO2 CH2O 6. C2H4 C2H2 C3H8 C2H6
carbon to carbon by single
covalent bond bond
carbons to carbons
7. CH3CH2OH CH3COCH3 8. CH3OCH3 CHONH2
carbon to
carbons by single covalent bonds oxygen separates the
carbons O
& N both bond to C
Bonus: CH2NH2COOH CH3COOCH2CH3
carbons to carbons by single covalent bonds -(NH2 hooks to first
carbon in #1)(-CH2CH3 also hooks to oxygen in#2)
