10/27 notes Flashcards
hybridization
the mixing of inequivalent orbitals to form new equivalent orbitals
why is hybridization used
to reconcile the orbital view with observed experiment bond lengths and angles
when do you have sp3 hybridization
4e- clouds
when do you have sp2 hybridization
3e- clouds
when do you have sp hybridization
2e- clouds
what type of bonds do single bonds always have
sigma bond
what two type of bonds do double bonds have
sigma and pi
what is overlap
opposite spin
what is head on overlap
a sigma bond
what is a sigma bond
free rotation around the bond
pi bond
side on overlap, no free rotation
bond angel between sp3 hybridized
109.5
what type of overlap occurs with pi bonds
side-on
what is a delocalized pi system
1)resonance structure where the pi bond moves
2)has alternating single and multiple bonds
what bonds are present in triple bond
sigma and pi
