A reaction was performed in which 4.0 g of cyclohexanol was reacted with an acid catalyst to obtain 2.8 g of cyclohexene. calcul

Answer:

%age Yield = 85.36 %

Solution:

The Balance Chemical Reaction is as follow,

C₆H₁₂O + Acid Catalyst → C₆H₁₀ + Acid Catalyst + H₂O

According to Equation ,

100 g (1 mole) C₆H₁₂O produces = 82 g (1 moles) of C₆H₁₀

So,

4.0 g of C₆H₁₂O will produce = X g of C₆H₁₀

Solving for X,

X = (4.0 g × 82 g) ÷ 100 g

X = 3.28 g of C₆H₁₀ (Theoretical Yield)

As we know,

%age Yield = (Actual Yield ÷ Theoretical Yield) × 100

%age Yield = (2.8 g ÷ 3.28 g) × 100

%age Yield = 85.36 %
