What is the mechanism for isoamyl acetate?
In reaction with isoamyl alcohol, one of the acyl from acetic anhydride will bind with isoamyl alcohol and discharge one H+ to form isoamyl acetate and acetic acid.
Then, excess acyl (from acetic acid) will react with excess alcohol to form another isoamyl acetate and water.
What is the mechanism of formation of isopentyl acetate?
The reaction mechanism involves initial protonation of the carboxyl group, nucleophilic attack by the hydroxyl, proton transfer, and loss of water followed by loss of the catalyzing acid to produce the ester.
The process is thermodynamically controlled yielding the most stable ester product.
How do you make isopentyl acetate?
.
1) Mix isopentyl alcohol (5.4 mL, via burette) and glacial acetic acid (8.5 mL, via graduated cylinder) in a round-bottom flask.
Carefully add 20 drops of conc.
H2SO4 to the mixture. .
2) Put in a few boiling chips and assemble the reflux apparatus (Figure 1).
Acetic acid (CH3CO2H) reacts with isopentyl alcohol (C5H12O) to yield isopentyl acetate (C7H14O2), a fragrant substance with the odor of bananas.

Step 1: Isopentyl alcohol does a nucleophilic attack on the carbonyl carbon of acetyl chloride to give a tetrahedral intermediate. Step 2: Collapse of the tetrahedral intermediate proceeds with loss of chloride anion. Step 3: The chloride anion does the deprotonation to give isopentyl acetate.
