Question
In the dichromate dianion :
Options
A.4Cr - 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
Solution
General structure of Cr2O72- may be written as :
Experimental determination shwos that bonds 1 to 6 aew identical bond lenght and 7 and 8 are also identical. The equal bond lengths of 6 bonds (1 to 6) isdue to resonance.
