Molecular Shape and Bonding Flashcards
1
Q
What is molecular orbital theory?
A
Number of atomic orbitals equals number of molecular orbitals (cant solve MO exactly for any molecule other than H2)
2
Q
What is the difference between anti-bonding and bonding orbitals?
A
Anti-bonding orbitals have more energy
3
Q
When p orbitals combine end on ____ bonds form, side on leads to ____ bonds
A
~Sigma
~Pi
4
Q
What is hybridisation?
A
When s and p orbitals are combined to form a hybrid orbital
5
Q
How does a C=C consist of a pi and sigma bond in ethene?
A
The sigma is via sp2 hybridised orbitals bonding.
The pi is via unhybridised p orbitals bonding side on.
