The prefix thio- refers to the presence of which element in a chemical compound?
Thio- Thio- The prefix thio-, when applied to a chemical, such as an ion, means that an oxygen atom in the compound has been replaced by a sulfur atom. This term is often used in organic chemistry. For example, from the word "ether," referring to an oxygen-containing compound having the general chemical structure R–O–R′, where R and R′ are organic functional groups and O is an oxygen atom, comes the word "thioether", which refers to an analogous compound with the general structure R–S–R′, where S is a sulfur atom covalently bonded to two organic groups. A chemical reaction involving the replacement
Chemical compound Chemical compound A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) composed of atoms from more than one element held together by chemical bonds. A chemical element bonded to an identical chemical element is not a chemical compound since only one element, not two different elements, is involved. There are four types of compounds, depending on how the constituent atoms are held together: A chemical formula is a way of expressing information about the proportions of atoms that constitute a particular chemical compound, using the standard abbreviations for the chemical elements, and subscripts to
