Ethyl alcohol is prepared industrially by the reaction of ethylene, $\mathrm{C}_{2} \mathrm{H}_{4},$ with water. What is the percent yield of the reaction if 4.6 $\mathrm{g}$ of ethylene gives 4.7 $\mathrm{g}$ of ethyl alcohol? $$\mathrm{C}_{2} \mathrm{H}_{4}(g)+\mathrm{H}_{2} \mathrm{O}(l) \longrightarrow \mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}(l)$$

Key Concepts

Percent Yield

Percent yield is a measure of the efficiency of a chemical reaction, calculated as the ratio of the actual yield obtained from the reaction to the theoretical yield predicted by stoichiometric calculations, multiplied by 100%. It helps in understanding the practical limitations and losses in a reaction process.

Theoretical Yield

The theoretical yield represents the maximum amount of product that can be produced from a given amount of reactants under ideal conditions. It is determined through stoichiometric calculations using the balanced chemical equation, assuming that all reactants are completely converted to products.

Stoichiometry

Stoichiometry is the branch of chemistry that involves calculating the relative quantities of reactants and products in chemical reactions. It uses the coefficients in a balanced chemical equation to determine the proportions needed for a complete reaction, thus enabling the calculation of theoretical yields.

Molar Mass

Molar mass is the mass of one mole of a substance, usually expressed in grams per mole (g/mol). It is used to convert between the mass of a substance and the number of moles, playing a crucial role in stoichiometric calculations and in determining the theoretical yield of a chemical reaction.
