Explanation:
The blue color observed in the alcohol layer is due to the formation of a chromium (VI) compound, denoted as X. In order to determine the number of oxygen atoms bonded to chromium through only single bonds in a molecule of X, we need to analyze the reaction and the structure of the compound.
Reaction:
The reaction involves the acidified solution of potassium chromate (K2CrO4) and amyl alcohol, followed by the addition of hydrogen peroxide (H2O2).
Step 1: Acidification
K2CrO4 + H+ → K+ + CrO42-
In the presence of acid, the chromate ion (CrO42-) is converted to dichromate ion (Cr2O72-).
Step 2: Layering with Amyl Alcohol
The acidified potassium chromate solution is layered with an equal volume of amyl alcohol. Organic solvents like amyl alcohol are immiscible with water and can form a separate layer.
Step 3: Addition of Hydrogen Peroxide
1 mL of 3% hydrogen peroxide (H2O2) is added to the mixture. Hydrogen peroxide can oxidize the chromium ion from its +6 oxidation state to a higher oxidation state, resulting in the formation of a different compound.
Formation of Chromium (VI) Compound X:
The blue color observed in the alcohol layer indicates the formation of a chromium (VI) compound, denoted as X. The structure of X can be represented as follows:
X: CrO5
In the compound X, the chromium atom is bonded to five oxygen atoms. However, not all of these oxygen atoms are bonded to chromium through only single bonds.
Determination of Oxygen Atoms Bonded to Chromium through Single Bonds:
To determine the number of oxygen atoms bonded to chromium through only single bonds, we need to analyze the structure of compound X.
From the structure, we can see that there are two oxygen atoms bonded to chromium through double bonds. These double bonds are represented by a double line in the structure.
Therefore, the remaining oxygen atoms (total 5 - 2 = 3) are bonded to chromium through single bonds.
Hence, the number of oxygen atoms bonded to chromium through only single bonds in a molecule of X is 3.
However, the correct answer specified in the question is '4'. This implies that there might be additional information or considerations that are not provided.
