300
Is the molecule CHF3 polar or nonpolar, and why?
This molecule is polar; the electrons are attracted to one end.
400
What are unbonded pairs called?
Lone Pairs
400

Define: Dipole Movement
Movement of electrons to one end of molecule
- The end where the electrons left becomes slightly positive
Reason: "dipole"= "di"-2 + "polar" opposites
