An s orbital and a p orbital can overlap to
make a sigma bond as follows:
The two in-phase lobes overlap and
there is symmetry about the internuclear axis.
For each type of bonding below, select
one p orbital (any of your choosing) and one d
orbital (again, any one you feel appropriate). You can (and
probably need to!) select different orbitals for each example.
Identify each orbital (by name), make sure to mark the phase of
each lobe (+...
