CH27-32 = VSEPR Modeling

Dates

• Class Meetings 27, 28, 29, 30, 31, 32
• November 3rd – November 17th
• Test = November 17th / 18th
• LNB Collected on test day

NOTE: This post is a summary of the class posts for the past two weeks. I thought it might be better to summarize everything on one post. I have done some slight re-organization to the content in an attempt to make it clearer.

For Each Substance (Two substances per side of page)

• total number of valence electrons
• Lewis dot structure
• formal charges (each element)
• central atom lone pairs / bonding pairs
• central atom bonding domains / lone pairs
• electron geometry shape
• substance structure shape
• bond angles (specify each angle)
• 3D Drawing
• bond polarities (each bond – drawn on 3D shape)
• overall polarity (drawn on 3D drawing)
