Hybridisation

(D) (A) NO2+=7+16 -1=22; CO2=6+16=22.

           So isoelectronic (both have 22 electrons in valence shells)

     (B) NO3-=7+24 +1=32; BF3=5+27=32.

          So isoelectronic and are isosturctural as both have trigonal planar structures.

         

  (C) NH3=7+3 =10So isoelectronic                          CH3-=6+3 +1=10 

 

  Both are pyramidal so isostructural.
