An acidified solution of potassium chromate was layered with an equal volume of amyl alcohol. When it was shaken after the addition of \( 1 \mathrm{~mL} \) of \( 3 \% \mathrm{~H}_{2} \mathrm{O}_{2} \), a blue alcohol layer was obtained. The blue color is due to the formation of a chromium (VI) compound \( X^{\prime} \). What is the number of oxygen atoms bonded to chromium through only single bonds in a molecule of\( \mathbf{X} \) ?
