Question

If 0.025 mol of cyclohexanol reacts with 0.011 mol of phosphoric acid, the theoretical yield of cyclohexene is

a) 0.011 mol
b) 0.025 mol
c) 0.036 mol
d) 0.013 mol

Answer 1

The maximum theoretical yield of cyclohexene depends on the amount of the limiting reagent, phosphoric acid. Since we have 0.011 mol of phosphoric acid, the theoretical yield of cyclohexene is also 0.011 mol.

Step-by-step explanation:

To calculate the theoretical yield of cyclohexene in a reaction where 0.025 mol of cyclohexanol reacts with 0.011 mol of phosphoric acid, we first need to understand the chemical equation:

Cyclohexanol → Cyclohexene + Water

The reaction has a 1:1 mole ratio between cyclohexanol and cyclohexene. Since we have 0.025 mol of cyclohexanol and only 0.011 mol of phosphoric acid, and the reaction is dependent on the stoichiometry of cyclohexanol, the amount of cyclohexene that can be produced will be determined by the limiting reagent.

In this case, phosphoric acid is the limiting reagent since there is less of it in moles compared to cyclohexanol. As such, the maximum amount of cyclohexene that can be formed is equal to the amount of phosphoric acid present, which is 0.011 mol. Thus, the theoretical yield of cyclohexene is 0.011 mol.
