Answer to Question #199393 in General Chemistry for Angelica

Question

1.    1.87 g of acetic acid (vinegar, C₂H₄O₂) reacts with 2.13 g of isopentyl alcohol (C₅H₁₂O) to yield isopentyl acetate (C₇H₁₄O₂), a fragrant substance with the odor of bananas. The reaction is:            C₂H₄O₂ + C₅H₁₂O ¾® C₇H₁₄O₂ + H₂O

 

a)       Which is the limiting reactant (LR) and excess reactant (ER)?

 

 

b)      How many grams of isopentyl acetate were formed?

 

 

c)       How many grams of the excess reactant is left after the reaction is complete?

 

 

 

 d)      If 2.96 g of isopentyl acetate was produced, what is the % yield of the reaction?

Answer 1

a) Limiting reactant (LR) =$C_2H_{10}O$

Excess reactant (ER)=$C_2H_4O_2$

b) Grams of isopentyl acetate formed=3.419g

c)Grams of the excess reactant=2.82g

d)Percent Yield =82.46%
