Question

An acidified solution of potassium chromate was layered with an equal volume of amyl alcohol. When it was shaken after the addition of 1 mL of 3% H₂O₂, a blue alcohol layer was obtained. The blue color is due to the formation of a chromium (VI) compound 'X' . What is the number of oxygen atoms bonded to chromium through only single bonds in a molecule of X?

Answer 1

Here the structure of CrO₅ is :-

Here, single bonded O-atoms with Cr is = 04
