hybridisation Flashcards
1
Q
what is sp2 hybridisation
A
when a 2s orbital hybridizes with 2 out of the 3 2p orbitals of am carbon atom to form 3 identical orbitals
these identical orbitals overlap to form a sigma bond between carbons
the pi bond is formed when the 2p orbitals overlap with eachother
2
Q
what is sp3 hybridisation
A
when carbon bonds to a molecule the electron from the 2s orbital moves to the 2p orbital and the 2s orbital is promoted
this then forms 4identical orbitals whach all overlap to form 4 sigma bonds
