Question

1. How are the properties of molecules related to the 3D distribution of electrons and Coulomb’s law? Provide evidence and reasoning to support your answer in 5-6 sentences.

2. Match each compound to the description of electron distribution between the atoms.

Cl₂, AgCl, PCl₃, C₂H₆O, CH₄

- Electrons transferred

- Unequal distribution of electrons

- Electrons equal distributed

3. Which bond is the most polar? H-O, H-F, H-N, H-C. Which (ones) of these substances have a smell? Si, P, CaCl₂, HOCl

5. Which molecules have a +1 formal charge on the central atom? Assume that the octet rule is satisfied. (Select all that apply.)

H₂CO, SO₂, NH₄⁺, CINO, CO₂, NO₃^-

6. Upload 2 drawings to illustrate if CH₃OH and C₂H₄ do or do not have a smell. Be sure that your drawings clearly illustrate the polarity of the bonds and the polarity of the overall molecule.
