This question makes no sense. Based on its wording I'd guess in the presence of the sun, but I don't think that's what you want to know.
Whenever silver is in the presence of certain sulphur compounds, particularly hydrogen sulphide.
Organic compounds are typically defined by the presence of carbon atoms bonded to hydrogen atoms. Compounds that contain carbon-hydrogen bonds are considered organic, while those that do not are classified as inorganic.
Compounds that contain both carbon and hydrogen are known as hydrocarbons. They can be classified into various categories, including aliphatic hydrocarbons (alkanes, alkenes, and alkynes) and aromatic hydrocarbons. These compounds are fundamental in organic chemistry and are the primary components of fossil fuels, plastics, and many biological molecules. The presence of carbon and hydrogen allows for a vast diversity of structures and properties, making hydrocarbons essential in numerous industrial and biological processes.
Vitamins are organic compounds the which are essential for nutrition. The first to determine the presence of vitamins in food was William Fletcher.

Compounds like hydrogen sulfide (H2S), hydrogen selenide (H2Se), and hydrogen telluride (H2Te) are expected to have a similar geometry to water. These compounds exhibit a bent or angular molecular geometry due to the presence of lone pairs of electrons on the central atom, similar to water's bent molecular structure.
The element that is found in all organic compounds is carbon. Organic compounds are primarily characterized by the presence of carbon atoms, which can form stable bonds with other elements, including hydrogen, oxygen, nitrogen, and more. This unique ability allows carbon to serve as the backbone for a vast array of molecular structures essential for life.
The presence of only oxygen and hydrogen does not necessarily indicate that a compound is organic. Inorganic compounds such as water (H2O) contain only oxygen and hydrogen as well. The organic/inorganic distinction is based on the type of chemical bonds present in the compound, with organic compounds containing carbon-carbon or carbon-hydrogen bonds.
The burning splint test is used to test for the presence of hydrogen. The symbol for hydrogen is H.
