NonPolar(NP) Molecules
Only Nonpolar bonds = Nonpolar molecule Nonpolar = sharing e- evenly Nonpolar Bond =
4
Polar Molecules If Not NP bond: 1. determine polarity of each Bond 2. Put in correct shape 3. Split in ½ a. 2 different charges = polar has poles= dipole b. same charge = nonpolar no poles

6
Ionic Bond kept together by…. Crystalline structure
7
Covalent Bond kept together by….interactions called IMF = intermolecular force
8
1. Hydrogen Bonding strongest
Highest Melting Point & Boiling Point Hydrogen attracted to: N itrogen O xygen F luorine

2. Dipole-Dipole [polar]
- end attracted /// to + end of another
![2. Dipole-Dipole [polar]](http://slideplayer.com/slide/14478198/90/images/9/2.+Dipole-Dipole+%5Bpolar%5D.jpg "- end attracted /// to + end of another.")

3. Dispersion [nonpolar] weakest
also known as Van der Waals & London Forces -a dipole is induced -lowest MP & BP interaction Induced + Induced -
