Chapter 3- Bonding Flashcards
1
Q
molecular orbitals
A
form when two atomic orbitals combine
2
Q
hybridization
A
way of making all the bonds to a central atom equivalent to each other
3
Q
hybrid orbitals
A
hybrid orbitals are formed by mixing different types of orbitals. use math to mix the following orbitals:
sp3
sp2
sp
4
Q
sp3
A
1 atom with all single bonds (sigma bonds).
tetrahedral geometry and no unhybridized p-orbitals to form pi bonds.
5
Q
sp2
A
1 double bond (1 sigma and 1 pi bond).
seen in alkenes. third orbital of each carbon is left unhybridized.
6
Q
sp
A
triple bond (1 sigma and 2 pi bonds)
to form a triple bond (alkynes). linear structure.
7
Q
resonance
A
describes delocalization of electrons in molecules that have conjugated bonds
8
Q
pi bond
A
formed by the parallel overlap of unhybridized p-orbitals
