Question

Using the following information, calculate the theoretical yield for the dehydration of 100.16 g of cyclohexanol. molar mass (g/mol) density (g/mL) cyclohexanol 100.16 0.948 cyclohexene 82.15 0.811

Answer 1

82.15g of Cyclohexene

Step-by-step explanation:

The reaction of dehydration of cyclohexanol (CycOH) to cyclohexene (CycENE) is:

CycOH + H₃PO₄ → CycENE + H₂O

That means, 1 mole of cyclohexanol produce 1 mole of cyclohexene.

Now, theoretical yield is defined as the maximum amount of product that could be obtained.

Thus, 100.16g of cyclohexanol could give as theoretical yield of cyclohexene:

100.16g CycOH × (1 mol / 100.16g) = 1 mole of CycOH = 1 mole of CycENE (Assuming a theretical yield).

1 mole CycENE × (82.15g / mol) =

82.15g of Cyclohexene
