Which of the following pairs of ions is isoelectronic and isostructural? CO32−NO3−CO_3^{2-} NO_3^- ClO3−CO32−ClO_3^- CO_3^{2-} SO32−NO3−SO_3^{2-} NO_3^- ClO3−SO32−ClO_3^- SO_3^{2-}

Multiple Choice Options

  • A CO32−,  NO3−C{O_3}^{2 - },\,\,N{O_3}^ - C O 3 _ 2 _ , N O 3 _ _
  • B ClO32−,  CO32−C{lO_3}^{2 - },\,\,C{O_3}^{2 - } C l O 3 _ 2 _ , C O 3 _ 2 _
  • C SO32−,  NO3−S{O_3}^{2 - },\,\,N{O_3}^ - S O 3 _ 2 _ , N O 3 _ _
  • D ClO3−,  SO32−Cl{O_3}^ - ,\,\,S{O_3}^{2 - } Cl O 3 _ _ , S O 3 _ 2 _

Step-by-Step Verified Solution

C O 3 2 _ ; 6 + 24 + 2 = 32; sp 2 ; trigonal planar N 3 _ : 7 + 24 + 1 = 32; sp 2 , trigonal planar So, these are isoelectronic as well as isostructural.
