Neet Solved Paper 2015 Question 8
Question: Which of the following pairs of ions are isoelectronic and isostructural?
Options:
A) $ CO_3^{2-},SO_3^{2-} $
B) $ ClO_3^{-},,CO_3^{2-} $
C) $ SO_3^{2-},NO_3^{-} $
D) $ ClO_3^{-},SO_3^{2-} $
Show Answer
Answer:
Correct Answer: D
Solution:
$ CIO_3^{-},=SO_3^{2-} $ Number of electrons $ CO_3^{2-}=6+2+24=32 $ $ SO_3^{2-}=16+2+24=42 $ $ CIO_3^{-}=17+24+1=42 $ $ CO_3^{2-}=6+24+2=32 $ $ NO_3^{2-}=7+2+24=33 $
Hence, $ CIO_3^{-} $ and $ SO_3^{2-} $ are isoelectronic and are pyramidal in shape.
