Chemical Bonding And Molecular Structure Question 73
Question: In the dichromate dianion
Options:
A) $ 4,Cr-O $ bonds are equivalent
B) $ 6,Cr-O $ bonds are equivalent
C) All $ Cr-O $ bonds are equivalent
D) All $ Cr-O $ bonds are non-equivalent
Show Answer
Answer:
Correct Answer: B
Solution:
Dichromate dianion has following structure $ {{[ O\to \underset{O}{\overset{O}{\mathop{\underset{\downarrow }{\overset{\uparrow }{\mathop{Cr}}},}}},-O-\underset{O}{\overset{O}{\mathop{\underset{\downarrow }{\overset{\uparrow }{\mathop{Cr}}},}}},\to O ]}^{2-}} $ 6, $ Cr-O $ bonds are equivalent.
