(a) NOTE : Isoelectronic species have same number of electrons and isostructural species have same type of hybridization at central atom.

NO3–; No. of e – = 7 + 8 * 3 + 1 = 32, hybridization of N in NO3– is sp3

CO32–; No. of e – = 6 + 8 * 3 + 2 = 32, hybridization of C in CO32– is sp3

CIO3–; No. of e – = 17 + 8 * 3 + 1 = 42, hybridization of CI in CIO3– is sp3

SO3; No. of e – = 16 + 8 * 3 = 440, hybridization of S in SO3 is sp2

? NO3– and CO32– are isostructural and isoelectronic.
