An acidified solution of potassium chromate was layered with an equal volume of amyl alcohol. When it was shaken after the addition of 1mL1mL of 33 % {H}_{2}{O}_{2}, a blue alcohol layer was obtained. The blue color is due to the formation of a chromium (VI) compound ′X′' X '. What is the number of oxygen atoms bonded to chromium through only single bonds in a molecule of XX?An acidified solution of potassium chromate was layered with an equal volume of amyl alcohol. When it was shaken after

Correct answer

4

Step-by-step solution

K2CrO4→H+/H2O2CrO5(DeepBluesolution){K}_{2}{CrO}_{4}\overset{{H}^{+} / {H}_{2}{O}_{2}}{\to}\mathop{{CrO}_{5}}_{( DeepBluesolution )}

An acidified solution of potassium chromate was layered with an equal volume of amyl alcohol. When it was shaken after

No. of oxygen atom bonded with chromium with single bond is (4)( 4 ).
