Chemical Bonding 12/17/07 Std 4.4

Objective: SWBAT practice determining shape and polarity of molecules.

Agenda:

• Attractive Molecules
• Shapes of Molecules
  

HW: Finish final draft of Attractive Molecules

• You need to go into full detail about why water has its particular shape and why it is polar. Be specific.
  
• Then explain why it was attracted to the charged rod. Once again, be specific!
  

VSEPR Theory Animation

From Holt, Reinhart, and Winston's Modern Chemistry

Chemical Bonding 12/13/07 (Std 4.4)

Objective: SWBAT determine if a molecule is polar.

Agenda:

• Attractive Molecules Lab
  

HW: write up conclusion for today's lab

A good conclusion:

• Restates the hypothesis (you answer to whether you thought water was going to be polar or not)
• Describes the results of the lab
• Uses the results to evaluate the hypothesis (relate what you observed to the hypothesis)

For this lab, your conclusions should relate the following concepts to the results that you observed:

• VSEPR Theory
• Geometry of the molecule (the shape)
• Polarity and electronegativity
