Adipic acid, C6H10O4, is a raw material for the making of nylon and it can be prepared in the laboratory by the following (unbalanced) reaction between cyclohexene, C6H10, and sodium dichromate, Na2Cr2O7 in sulfuric acid: C6H10(l) + Na2Cr2O7(aq) + H2SO4(aq) ® C6H10O4(aq) + Cr2(SO4)3(aq) + Na2SO4(aq) + H2O There are side reactions that reduce the yield of adipic acid. Losses of product during its purification also reduce the overall yield. A typical yield of purified adipic acid is 68.60%.

Question

Adipic acid, C₆H₁₀O₄, is a raw material for the making of nylon and it can be prepared in the laboratory by the following (unbalanced) reaction between cyclohexene, C₆H₁₀, and sodium dichromate, Na₂Cr₂O₇ in sulfuric acid:

C₆H₁₀(l) + Na₂Cr₂O₇(aq) + H₂SO₄(aq) ® C₆H₁₀O₄(aq) + Cr₂(SO₄)₃(aq) + Na₂SO₄(aq) + H₂O

There are side reactions that reduce the yield of adipic acid. Losses of product during its purification also reduce the overall yield. A typical yield of purified adipic acid is 68.60%.

Balance the equation.
How many grams of cyclohexene are needed to prepare 12.5 grams of purified adipic acid, which is a 68.60% yield?
The only available supply of sodium dichromate is its dihydrate, Na₂Cr₂O₇2H₂O. Since the reaction occurs in an aqueous medium, the water in the dihydrate causes no problems, but it does contribute to the mass of what is taken of this reactant. How many grams of this dihydrate are also required in the preparation of 12.5 grams of purified adipic acid, which is a yield of 68.60%?

Expert Solution

Step 1

1. The balanced chemical equation is -

3C₆H₁₀ (l) + 4Na₂Cr₂O₇ (aq)+ 16H₂SO₄ (aq) $\to$ 3C₆H₁₀O₄ (aq) + 4Cr₂(SO₄)₃ (aq) + 4Na₂SO₄ (aq) + 16H₂O
