While the carbonyl stretching frequency for simple aldeydes, ketones, and carboxylic acids is about 1710 cm^-1, the carbonyl stretching frequency for esters is about ________.

A) 1660 cm^-1
B) 1700 cm^-1
C) 1735 cm^-1
D) 1800 cm^-1
E) 2200 cm^-1

Carbonyl Stretching Frequency

Refers to the specific vibration frequency observed in infrared spectroscopy for the carbon-oxygen double bond in carbonyl groups, typically around 1650 to 1750 cm^-1.

Esters

Organic compounds derived from carboxylic acids in which the hydrogen of the carboxyl group is replaced by a hydrocarbon group, often responsible for the sweet or fruity aromas and flavors of many fruits and flowers.

Aldehydes

Organic compounds characterized by a carbonyl group bonded to at least one hydrogen atom, making them highly reactive.
