Question: Calculate the theoretical yield of isopentyl acetate for the esterification reaction. isopentyl alcohol- quantity: 4.37 g molar mass (g/mol): 88.15 acetic acid- quantity: 8.5 mL molar mass: 60.05 isopentyl acetate (product)- molar mass:88.15 Would appreciate steps.

Synthesis of Isopentyl Acetate. Introduction: The purpose of this lab is to perform a Fischer Esterification reaction. To do this, an alcohol, isopentyl alcohol, will be reacted with a carboxylic acid, acetic acid. The purpose of this reaction will be the formation of an ester, isopentyl acetate.

Isopentyl Acetate (Banana Oil)- IR Spectrum. I need help in assigning the following IR peaks: alkane C–H stretch, C=O stretch, alkane CH2 bend and C–O stretch .

How great is the molar excess? The limiting reagent used in this experiment is the isopentyl alcohol while the reagent used in excess is the acetic acid. The molar excess is about 1.5 – 1.75 times greater than the amount that is theoretically yielded. 5. Outline a separation scheme for isolating pure isopentyl acetate from the reaction mixture.

Calculate the theoretical yield and percent yield of isopentyl acetate for the esterification reaction. Reagents used: Isopentyl Alcohol quantity: 16.3mL. Acetic Acid: 17 mL. Sulfuric Acid: 1mL-----Product: Isopentyl Acetate: 9.5989 g-----Note: In the lab, it said that an excess of acetic acid was used to drive the reaction toward completion.

If the alcohol were not significantly water-soluble like in the reaction of acetic acid with isopentyl alcohol to form isopentyl acetate, the carboxylic acid would be used in excess. Here, the ester and the alcohol have similar solubilities in water (14 mg/mL vs. 54 mg/mL) and similar boiling points (142 °C vs. 130 °C) as well, which would ...
