Chemical Bonding And Molecular Structure Question 383
Question: Which of the following has $ p\pi -d\pi $ bonding [CBSE 2002]
Options:
A) $ NO_3^{-} $
B) $ CO_3^{-2} $
C) $ BO_3^{-3} $
D) $ SO_3^{-2} $
Show Answer
Answer:
Correct Answer: D
Solution:
$ :\overset{..}{\mathop{O}},=\underset{\underset{..}{\mathop{O:}},}{\mathop{\underset{||}{\mathop{S,}},}},=\overset{..}{\mathop{O}},: $ 5 atoms has 12 electrons in its outermost shell. One $ (S-O)\pi $ bond will be (p-p) p bond while two $ (S-O)\pi $ bond will be (p-d) p bond.
