Your electron geometry is tetrahedral. What is your hybridization?
sp3
Your electron geometry is trigonal planar. What is your hybridization?
sp2
Your electron geometry is linear. What is your hybridization?
sp
How many unhybridized p-orbitals are present in a sp3 hybrid?
0
How many unhybridized p-orbitals are present in a sp2 hybrid?
1
How many unhybridized p-orbitals are present in a sp hybrid?
2
What is σ bond?
Overlap between hybridized and unhybridized orbitals
What is a π bond?
Side-ways “overlap”of unhybridized p-orbitals
Which is stronger?
A σ bond or a π bond?
σ bond
Define constructive overlap
What does it result in?
Orbitals that are in phase (have the same sign) add together
Results in a bonding Molecular Orbital (σ MO)
Define destructive overlap
What does it result in?
Orbitals that are out of phase (have the opposite sign) cancel out
Results in an antibonding* Molecular Orbital (σ* MO)
Can you do a bond rotation around single bonds? Why or why not
Yes, this is usually permitted due to the symmetry of σ MOs.
Can you do a bond rotation around a double bond? Why or why not?
No, the symmetry of the π MO restricts rotation (i.e. you will break the π bond)
