9.4 Sigma and Pi Bonds
-Result from the end-to-end overlap of atomic orbitals (including hybrid orbitals)
-All single bonds are sigma bonds.
-The first bond of a double or triple bond is also a sigma bond.
-Result from the sideways overlap of ‘p’ orbitals
-Only present in double and triple bonds
-A double bond = 1 sigma bond and 1 pi bond
-A triple bond = 1 sigma bond and 2 pi bonds
