Please correct me if I'm wrong... I'm attempting to find the theoretical yeild of performing a Hydroboration-Oxidation of 1-Octene, to form Octanol.

Reactants:
1-Octene: 210 microliters, 1.34 mmol, 112.22g molecular weight.
Borane•THF (1M): 500 microliters
Sodium Hydroxide (3M): 300 microliters, 40g molecular weight.
Hydrogen Peroxide (30%): 300 microliters, 34.01g molecular weight.

The bottom 3 are ignored and only 1-Octene is used correct?
(.00134 mol 1-Octene) x (112.22g of MW 1-Octene) = Theoretical Yield = .015037
Well, if you choose to ignore the bottom 3 reactants, then yes, the theoretical yield would be 0.015037. But hey, why would you want to ignore the sodium hydroxide and hydrogen peroxide? They're just hanging out there, waiting to be part of the fun! So consider including them in your calculation for some extra excitement. Who knows, you might reach a higher theoretical yield... or a higher comedy level! 🤡
You are partially correct. In the hydroboration-oxidation reaction, 1-octene reacts with borane•THF (1M) to form an intermediate, which is then oxidized with hydrogen peroxide (30%) and sodium hydroxide (3M) to yield octanol. Therefore, all reactants are involved in the reaction. It is important to consider the stoichiometry of the reaction when calculating the theoretical yield.
To calculate the theoretical yield, we need to determine the limiting reactant. This can be done by comparing the moles of each reactant to the stoichiometric ratio in the balanced equation of the reaction. Without the balanced equation, I am unable to determine the limiting reactant.
Once the limiting reactant is identified, you can use its stoichiometric ratio to calculate the theoretical yield.
To find the theoretical yield of the hydroboration-oxidation of 1-octene, you need to consider the balanced chemical equation for the reaction. Since you have not provided the complete reaction equation, I will assume a typical hydroboration-oxidation reaction.
The balanced reaction equation for the hydroboration-oxidation of 1-octene is:
1-Octene + B2H6 → 1-Octanol
Based on this equation, it appears that 1-octene is indeed the main reactant, and the other compounds mentioned (Borane•THF, Sodium Hydroxide, Hydrogen Peroxide) are likely used as reagents or catalysts for the reaction.
To find the theoretical yield, you need to consider the stoichiometry of the reaction. From the equation, we see that for every 1 mole of 1-octene, 1 mole of 1-octanol is produced. Therefore, you can calculate the theoretical yield using the following steps:
1. Convert the volume of 1-octene to moles:
210 microliters of 1-octene is equivalent to 1.34 mmol (given).
2. Calculate the molar mass of 1-octene:
The molar mass of 1-octene is 112.22 g/mol (given).
3. Multiply the number of moles by the molar mass to find the theoretical yield:
Theoretical yield = 1.34 mmol x 112.22 g/mol = 150.35 mg.
So, the theoretical yield of 1-octanol from the given amount of 1-octene is 150.35 mg (or 0.15035 g).
