VSEPR Theory: Shapes of Molecules - Part A

 

Part A -- Part B -- Part C -- Part D -- Part E -- Part F
Part G
-- Part H -- Part I -- Part J -- Part K

 

When working on VSEPR experiment:

 

1. Completely answer all questions and fill in all blanks

 

2. Draw all Lewis structures

 

3. If present, show nonbonding electron pairs (or lone pairs) on both central and non-central atoms in Lewis structures

 

4. Draw all three-dimensional molecular shapes

 

5. Show correct bond angles and three dimensions in molecular shapes

a. Bonds represented by lengthened triangles indicate bonds/positions coming toward you and point out the front of the two-dimensional paper.

 

b. Bond represented by lengthened dashed triangles or dashed lines indicate bonds/positions going away from you and pointing out the back of the two-dimensional paper.
