PART I
1. On a separate piece a paper, write your name.
2. For each of the following compounds:
- Draw the Lewis structures
- Indicate resonance forms (if applicable)
- Provide:
- electron geometry
- molecular shape (geometry) for each central atom
- bonding electrons
- lone pair electrons.
- Thiocyanate ion (SCN-), C-central atom
- Nitrate ion (NO3-). N-central atom
- Ammonium ion (NH4+). N-central atom
- Formaldehyde (H2CO). C-central atom
- Dichlorodifluoromethane (CCl2F2). C-central atom
- Cyanide ion (CN-). C-central atom
- Hydrogen cyanide (HCN) . C-central atom
- Methanimine (CH2NH). 1st: C-central atom, 2nd: N- central atom
- Hydrogen peroxide (H2O2). O-central atom
- Sulfite ion (SO32-). S-central atom
Take a picture of your drawings and submit as a pdf file. Please include your name. (20 points)
This chart below will help you to determine the electron geometry and molecular shape (geometry)
