Question

What is the chemical formula for coffee?

Answer 1

Coffee contains about 1,000 chemical components, and the molecular and physiological impacts of these chemicals are current study topics in food chemistry. Coffee's chemical complexity is becoming apparent, particularly in light of physiological consequences that cannot be attributed only to the presence of caffeine. Furthermore, coffee has a high concentration of antioxidants including chlorogenic acids, hydroxycinnamic acids, caffeine, and Maillard reaction products like melanoidins. Alkaloids and caffeoylquinic acids are popular insecticides, and their effects on coffee quality and flavour have been studied in the majority of research.

Complete answer:
We talk about caffeine here,
The coffee "bean" (the seed of the coffee plant), from which coffee is made, is the world's major source of caffeine. The amount of caffeine in coffee varies a lot depending on the type of bean and how it's prepared; even beans from the same bush might have different levels of caffeine.
Caffeine has the chemical formula ${{C}_{8}}{{H}_{10}}{{N}_{4}}{{O}_{2}}$ and is also known by the IUPAC designation 1, 3, 7-Trimethylpurine-2,6-dione. Caffeine may be present in a variety of foods and drinks that we eat on a daily basis, including coffee and tea. Caffeine content in coffee and tea leaves is limited to 5%. Caffeine is made in chemistry labs by combining dimethylurea with malonic acid.
Caffeine is a pyrimidinedione and imidazole ring that has been fused together to produce an alkaloid. A pyrimidinedione ring is a 6-member ring with two nitrogen atoms, whereas an imidazole ring is a 5-member ring with two nitrogen atoms.

Note:
Caffeine belongs to the methylxanthine class of central nervous system stimulants. It is the most frequently used psychoactive substance on the planet. It is lawful and uncontrolled in almost all regions of the world, unlike many other psychoactive drugs. Caffeine has a number of recognised mechanisms of action that may be used to explain its effects. The most notable benefit is that it reversibly inhibits adenosine's effect on receptors, preventing the development of sleepiness caused by adenosine. Caffeine also activates the autonomic nervous system in several ways.
