What reactant is needed to combine pentanol to produce pentyl propanoate?
All you need is propanoic acid. Added in an condensation reation.
The word "excess" is used in chemistry primarily to compare the amount of one reactant available for reaction with the amount of a different such reactant. The reactant that is present in more than sufficient amount to react completely with all the other reactants, to produce the expected product(s), is present in "excess".
Limiting reactants are the reactants that are used up first. And once they are used up, they stop, or limit, the reaction. So the amount of product that can be produced depends on the limiting reactant. The other reactant, the one in excess, would predict a larger amount of product. But once we produce the amount of product predicted by the limiting reactant. The limiting reactant is used up and the reaction stops.
The limiting reactant is the reactant which governs the amount of product(s) yielded in a chemical reaction. This quantity is calculated using the stoichiometry of a given reaction. The excess reactant is thus not used in calculating the theoretical yield. For example, consider a reaction 4A + B = 2C, with 4mol A and 2mol B. A is the limiting reagent because it can only produce 2mol C based on the stoichiometry, whereas B could…
This is an esterification reaction that produces pentyl ethanoate as its product. If I remember correctly, pentyl ethanoate smells of pear drops. The general rule here is that any alc1ohol will react with any alk2anoic acid to produce the corresponding ester alk1yl alk2anoate. Oh, and it's pentan-1-ol btw, not 1-pentanol.
