CONCLUSIONS:
(1)
  Atoms of second period elements follow octed rule in doing so either they accept co-ordinate bond or they form co-ordinate bond.  However atoms of 3rd period elements perfectly form double bond (pi bond) in the place of co-ordinate bond if direction of co-ordinate bond is from centre to substituent.
(2) If maximum covalency rule applied and pi bonds have formed then back bond is not considered in species
For example H2SO4 and HClO4  have no back bond there is double bond.
