Definitions:

Ketones

Organic compounds characterized by a carbonyl group (C=O) bonded to two carbon atoms, important in many biological and industrial processes.

Acid Chlorides

Organic compounds derived from acids by substituting a hydroxyl group with a chlorine atom, known for their reactivity.

1710 cm^-1

This number typically represents the absorption peak in infrared spectroscopy corresponding to the stretching vibration of a carbonyl (C=O) group in a compound.

Carbonyl Stretching

A vibrational mode observed in infrared spectroscopy, indicative of the C=O group's stretching within a molecule.
