p?-p? and p?-d? bonding

p?-p? Bonding

When one p-orbital of one atom is vacant and the other atom has a lone pair of electrons then if this lone pair is donated to the vacant p-vacant orbital then the type of bond formed is known as p?-p? bonding. 

For example, Boron ib BF3 has one empty p-orbital and p-orbital of fluorine contains lone pair, thus in this case boron acts as a Lewis acid and fluorine as a Lewis base. Thus, Fluorine donates its lone pair to boron and thus forms p?-p? bonding.

 

p?-d? Bonding

When one d-orbital of one atom is vacant and the other atom has a lone pair of electrons then if this lone pair is donated to the vacant d-vacant orbital then the type of bond formed is known as p?-d? bonding. In other words, p?-d? bond is formed when p orbital of one atom and d orbital of another atom overlap laterally.

For example, PO43- has a p?-d? bonding because the lateral overlap of p-orbital of oxygen atom with d-orbital of sulphur atom occurs.
