How can you tell the hybridization of a given molecule?
sp3, sp2, sp or none?

dunno if you've gone over sigma/pi bonding, but:
a single bond results from a single sigma bond
a double bond is from a sigma bond and a single pi bond
a triple bond results from a sigma bond and two pi bonds
pi bonds are formed by unhybridized p orbitals, so the more free p orbitals you have (more pi bonds), the fewer p orbitals were hybridized. that means that usually if an atom only has single bonds it will be sp3 hybridized. a double bond = sp2, and a triple = sp
hope that helps.

Look at the geometry around the central atom of the molecule. If it is a linear molecule, the bonding is usually sp. If the geometry is trigonal planar, then the bonding is sp2. When the geometry is tetrahedral, the bonding is sp3.
