Hybridisation
How does hybridisation occur?
Atomic orbitals change shape and energies for the best overlap and bonding
Atomic orbitals change size and energies for the best overlap and bonding
Atomic orbitals don't change shape and energies for the best overlap and bonding
Atomic orbitals change shape but not energies for the best overlap and bonding
What orbitals interact to give a sigma bond?
Two s orbitals
Two pz orbitals
An s orbital and a pz orbital
All
What orbitals interact to give a pi bond?
Hybridised pz orbitals
Hybridised py orbitals
Non hybridised pz orbitals
Non hybridised py orbitals
Looking at the central atoms, which 3 molecules have sp2 hybridisation?
GaBr3, CH3+,PH3
GaBr2,CH4,PH3
NH3,CH3+,PH3
NH3,CH3+,GaBr3
In sp2 bonding, what angle is the non hybridised p orbitals, in relation to the hybridised orbitals?
45 degrees
180 degrees
90 degrees
60 degrees
Why is the hybridisation for phosphorus in PCl5 sp3d?
Phosphorus is electronegative
Phosphorus can expand its octet
Phosphorous has 5 valence electrons
Phosphorous can expand its d orbital
Why is the triple bond on carbon 2 stronger than the single bond on carbon 1 in CH3CCH?
More s characteristics
More p characteristics
More hybridised orbitals
Less hybridised orbitals
Why is the hybridisation for nitrogen in NH3 and CH3CONH2 different?
Localised electrons aren't fixated
Delocalised electrons are fixated
Localised electrons share electron density
Delocalised electrons share the electron density
What does the hybridisation of CH3CONH2 result in?
An unstable structure
A resonance structure
A racemic structure
A resonance hybrid structure
