Bellwork- Polar ammonia
1)Draw a 3D sketch of ammonia (NH3)
2)What is the shape of this molecule?
3)Why does the molecule have this shape?
4)Show the bond and molecule polarity on the sketch.
5)Would this molecule be polar if it was planar?
Know your pet molecules!
CH4 NH3 H2O CO2 CH2OI may replace H’s with Cl or F to make polar bonds!
Intermolecular forces are forces between two or more molecules
Intermolecular forces
Intermolecular attractions are weaker than either ionic or covalent bonds.
These attractions determine whether a molecular compound is a gas, a liquid, or a solid at a given temperature.
