AP Orbital Hybridization Concepts Flashcards
1
Q
What is the orbital hybridization of linear, trigonal planar, and tetrahedral molecules?
A
linear –> sp
trigonal planar –> sp^2
tetrahedral –> sp^3
2
Q
What is a sigma bond?
A
a bond directly between two atoms
3
Q
What is a pi bond?
A
an electron pair on the central atom (they are above and below the sigma bonds)
