How do you identify ester?

Esters can be identified through several methods. One common technique is infrared (IR) spectroscopy, where esters typically show a strong absorption band around 1735-1750 cm⁻¹ due to the carbonyl (C=O) group and a series of peaks around 1000-1300 cm⁻¹ attributed to C-O stretching. Additionally, esters can be recognized by their characteristic fruity odors and can be confirmed through chemical tests, such as hydrolysis, which produces the corresponding acid and alcohol.
