Why electron density is more in ortho & para positions? Why meta position is unfavourable in most cases?

Expert Answer:

It depends on the functional group already present on the ring. If the group already present is activating, it will donate electron density to the ring pi-system. Through resonance this electron density will be available partly at o- and p-positions.
