We had a late arrival!!
What we did in class:
1. Went over the homework that was due yesterday
2. Took notes on Intermolecular Forces
3. Stared working on the Hw worksheets
Intermolecular Forces:
There are three kinds
- London Dispersion Forces
- Dipole Dipole Force
- Hydrogen bonding
The london dispersion method is also known as the Van Der Waals forces. It includes Dipole between non-polar molecules to create a temporary attraction. Electrons can flow more in one direction than another, eventually temporary dipole. The attraction is weak and short lived
The dipole dipole force is in between polar molecules. It when the + of one molecule attracts the - of another. The attraction is a permanent one.
Hydrogen Bonding is like dipole on steroids. It only happens when the H of one molecule attracts a F, O, or N of another molecule.
HW:
1. Webassign due tonight by 11:59pm
2. Two IMF worksheets that we picked up at the beginning of class
3. Start the review packet!!! The test is this friday!!!!
It's the 5th ;)
