Final answer:
To find the limiting reagent in the reaction producing t-pentyl chloride, we must calculate and compare the moles of t-pentyl alcohol and hydrochloric acid relative to the balanced chemical equation.
Step-by-step explanation:
The limiting reagent in the nucleophilic substitution reaction forming t-pentyl chloride from t-pentyl alcohol and hydrochloric acid is determined by comparing the stoichiometry of the reaction with the amounts of each reactant provided. We need to calculate the number of moles of t-pentyl alcohol and hydrochloric acid and compare these with the stoichiometric coefficients in the balanced equation for the reaction. Considering typical molar masses and concentrations, the reactant with the fewer moles relative to its stoichiometric requirement is identified as the limiting reagent. This reactant will be completely consumed during the reaction, while the other reactant will be in excess.
