Consider the reaction of cyclohexanol and an acid catalyst to obtain cyclohexene.

cyclohexanol (100.16 g/mol) --> cyclohexene (82.14 g/mol)

a reaction was performed in which 3.1 g of cyclohexanol was reacted with an acid catalyst to obtain 2.2 g of cyclohexene. calculate the percent yield for this reaction (in %).

Answer : The percent yield of the reaction is, 86.5 %

Solution : Given,

Mass of Cyclohexanol = 3.1 g

Molar mass of Cyclohexanol = 100.16 g/mole

Molar mass of Cyclohexene = 82.14 g/mole

First we have to calculate the moles of Cyclohexanol.

Now we have to calculate the moles of Cyclohexene.

The balanced chemical reaction is,

From the reaction, we conclude that

As, 1 mole of Cyclohexanol react to give 1 mole of Cyclohexene

So, 0.03095 mole of Cyclohexanol react to give 0.03095 mole of Cyclohexene

Now we have to calculate the mass of Cyclohexene.

Theoretical yield of Cyclohexene = 2.542 g

Experimental yield of Cyclohexene = 2.2 g

Now we have to calculate the percent yield of reaction.

Therefore, the percent yield of the reaction is, 86.5 %
