Definitions:

Carbonyl Compounds

Organic compounds that contain a carbonyl group (C=O) as part of their structure, including ketones, aldehydes, carboxylic acids, and amides.

Equilibrium Constants

A dimensionless number representing the ratio of product concentrations to reactant concentrations at equilibrium, with each concentration raised to the power of its coefficient in the balanced equation.

Aldehydes

Organic compounds characterized by the presence of a carbonyl group bonded to at least one hydrogen atom, typically found at the end of a molecule.

Ketones

Organic compounds characterized by a carbonyl group (C=O) bonded to two carbon atoms, prominent in many biological and synthetic contexts.
