Question

A reaction was performed in which 3.7 g of cyclohexanol was reacted with an acid catalyst to obtain 2.6 g of cyclohexene. calculate the theoretical yield for this reaction.

Answer 1

Answer:- 3.0 g

Solution:- Cyclohexanol gives cyclohexene on acid catalysis. Water molecule is actually given out in the reaction.

$cyclohexanol\overset{acid}{\rightarrow}cyclohexene+H_2O$

There is 1:1 mole ratio between cyclohexanol and cyclohexene. Let's calculate the theoretical yield of cyclohexene using stoichiometry as:

$3.7gcyclohexanol(\frac{1moleCyclohexanol}{100.16gCyclohexanol})(\frac{1moleCyclohexene}{1moleCyclohexanol})(\frac{82.14gCyclohexene}{1moleCyclohexene})$

= 3.0 g Cyclohexene

Therefore, the theoretical yield of cyclohexene is 3.0 g.
