Which of the following pairs of ions are isoelectronic and isostructural? [NCERT Exemplar]

Answer» OPTION  DEXPLANATION:Isostructural chemical compounds have similar chemical structures. ISOELECTRONIC terms refer to two atom, ions or molecules that have the same number of valence electrons. ClO  3 − ​   =SO  3 2− ​     Number of electrons- CO  3 2− ​   =6+2+24=32 SO  3 2− ​   =16+2+24=32 ClO  3 2− ​   =17+24+1=42 NO  3 2− ​   =7+2+24=33 Hence, ClO  3 2− ​    and SO  3 2− ​    are isoelectronic and pyramidal in shape. Option D is the CORRECT answer.
