Areaction was performed in which 3.8 g of cyclohexanol was reacted with an acid catalyst to obtain 2.7 g of cyclohexene. calculate the theoretical yield for this reaction.

              Theoretical Yield =  3.11 g

               %age Yield = 86.81 %

The Balance Chemical Equation is as follow,

                    C₆H₁₂O  +  Catalyst     →     C₆H₁₀  +  H₂O  +  Catalyst

Where;

           C₆H₁₂O  =  Cyclohexanol

           C₆H₁₀  =  Cyclohexene

Calculating Theoretical Yield:

According to equation,

                100.16 g (1 mol) of C₆H₁₂O produces  =  82.15 g (1 mol) of C₆H₁₀

So,

                         3.8 g of C₆H₁₂O will produce  =  X g of C₆H₁₀

Solving for X,

                      X  =  (3.8 g × 82.15 g) ÷ 100.16 g

                      X  =  3.11 g of C₆H₁₀

Theoretical Yield =  3.11 g

Calculating %age Yield:

As,

                       %age Yield  =  Actual Yield ÷ Theoretical Yield × 100

So,

                       %age Yield  =  2.7 g ÷ 3.11 g × 100

                       %age Yield = 86.81 %

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
