Starting with 2.10 g of cyclohexanol, what is the theoretical yield of cyclohexane in moles?

Molecular Weight (MW) of Cyclohexanol = 100.2 g/mol
Molecular Weight (MW) of Cyclohexene = 82.1 g/mol

a) 0.026 mol
b) 0.032 mol
c) 0.022 mol
d) 0.018 mol

Answer :

Final answer:

The theoretical yield of cyclohexane in mol is 0.0209 mol.

Explanation:

To find the theoretical yield of cyclohexane in moles, we need to determine the molar ratio between cyclohexanol and cyclohexane. The molar mass of cyclohexanol is 100.2 g/mol, while the molar mass of cyclohexane is 82.1 g/mol.

First, convert the mass of cyclohexanol to moles: 2.10 g / 100.2 g/mol = 0.0209 mol. Then, use the molar ratio between cyclohexanol and cyclohexane to find the theoretical yield of cyclohexane: 0.0209 mol cyclohexanol * (1 mol cyclohexane / 1 mol cyclohexanol) = 0.0209 mol cyclohexane Therefore, the theoretical yield of cyclohexane in mol is 0.0209 mol, which is option d) 0.018 mol.
