Of the following sets which one does NOT contain isoelectronic species?

Multiple Choice Options

  • A BO33−BO_3^{3 - } , CO32−CO_3^{2 - } , NO3−NO_3^{- }
  • B SO32−SO_3^{2 - } , CO32−CO_3^{2 - } , NO3−NO_3^{-}
  • C CN−CN^{- } , N2N_2 , C22−C_2^{2 - }
  • D PO43−PO_4^{3 - } , SO42−SO_4^{2 - } , ClO4−ClO_4^{ - }

Step-by-Step Verified Solution

In SO32−SO_3^{2 - } no of electrons = 16 + 24 + 2 = 42

In CO32−CO_3^{2 - } no of electrons = 6 + 24 + 2 = 32

In NO3−NO_3^{-} no of electrons = 7 + 24 + 1 = 32

So they are not isoelectronic.
