Draw the structural formula for the major organic product(s) formed when acetyl chloride reacts with butanol in pyridine.

Acyl chloride is considered as the most reactive derivative of carboxylic acids. Acetyl chloride when reacted with Butanol produces Butyl Acetate as a Mojor product.
This reaction is carried out in the presence of pyridine. Pyridine acts as a catalyst. And this catalyst is often used in esterification reactions.
The reaction along with mechanism is shown below,
