Lesson Plan: Polar Bonding Chemistry • Second Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to identify polar bonds within molecules and assess their effect on the polarity of the molecule as a whole.
Objectives
Students will be able to
- explain the difference between ionic, polar, and covalent bonds,
- compare the electronegativity of atoms in a bond to identify when bonds are polar,
- assign partial charges to the atoms of a polar bond,
- analyze polar bonds, bond angles, and the stereochemistry of a molecule to deduce whether the molecule is a permanent dipole,
- construct dipole moments for a variety of molecules.
Prerequisites
Students should already be familiar with
- electronegativity,
- formation of ionic and covalent bonds,
- simple knowledge of structures.
Exclusions
Students will not cover
- VSEPR,
- quantitative evaluation and comparison of dipole moments in debyes.
