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 %   H 2 O 2 , 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 ?

Correct answer

4

Step-by-step solution

K 2 CrO 4 → H + / H 2 O 2 CrO 5 ( Deep Blue solution ) No. of oxygen atom bonded with chromium with single bond is ( 4 ) .
