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.

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
