Which of the two ions from the list given below that have the geometry that is explained by the same hybridization of orbitals, NO2-,NO3- NH2-,NH4+,SCN-??

NO2-and NO3- both have same hybridization,  i.e. sp2No. of hybrid orbitals(H.O) = 12V+M±Cwhere, V=no. of valence electrons on central atom,            M=no. of monovalent atoms,            C=charge.In case of cation consider ‘-C’ , In case of anion consider ‘+C’For NO2- , no. of H.O=125+0+1=3 (SP2 hybridization)For NO3- , no. of H.O=125+0+1=3 (SP2 hybridization)
