Bond Polarity

The first thing we did in class was go over homework.

Then, most of class time was spent on a partner quiz.

Lastly, we went over some notes on polarity:

There are 2 kinds of polarity

• Bond Polarity
• The electronegativity difference between two atoms
• 0.0-0.4= non polar 0.4-1.7=polar 1.7-infinity=ionic
• Example: ẟ- (partial negative) N <--+ C ẟ+

                                                                      3.0   -    2.5= .5

• The arrow denotes the more electronegative side, while the plus sign indicates the positive side.
• Molecule polarity:
