Friday January 31st

We took a partner quiz that took a majority of the class period

And we started taking some notes about Polarity

There are 2 kinds of Polarity:

• Bond Polarity
• electronegativity differences between 2 atoms

ex. N  <---+ C

    3.0          2.5 

The arrow points to N because the electrons have a stronger pull toward it. 

And since 3.0-2.5 is 0.5 the bond is a POLAR covalent bond.

• Molecule Polarity

We didn't finish the notes in class

Homework:

We have a WebAssign due SUNDAY night. You'll need your textbook.

I will be blogging on Monday again.
