Chemical Bonding And Molecular Structure Question 529
Question: The isoelectronic pair is
[AIIMS 2005]
Options:
A) $ Cl_2O,\ ICl_2^{-} $
B) $ ICl_2^{-},ClO_2\ $
C) $ IF_2^{+},\ I_3^{-} $
D) $ ClO_2^{-},\ CIF_2^{+} $
Show Answer
Answer:
Correct Answer: D
Solution:
Number of electrons in $ClO_2$ = 7 + 6 + 6 + 1 = 20
Number of electrons in $ClF^{2+}$ = 7+7+7 - 1=20.
