## Abstract

The origins of planets, and perhaps life itself, is intrinsically linked to the chemistry of planet formation. In this chapter we will attempt to explore the chemistry of planet-forming disks from the perspective of knowledge gained from decades of solar system study, combined with our rapidly growing knowledge of extra-solar protoplanetary disks. Our aim is not to provide a comprehensive survey of the literature, but rather to present the chemical and physical tools that are used to explore chemical evolution during the earliest stages of planet formation. We include a discussion of observational constraints from our solar system and extra-solar disks, thermodynamic equilibrium and chemical kinetics, and the physical prescriptions for various important aspects (X-ray/UV irradiation, thermal structure, molecular adsorption/desorption, ..) that are used in current models. The chapter is aimed for young researchers.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
