The correct spelling of "diiodobenzene" is a bit complex, but it can be explained using the IPA phonetic transcription. The word is pronounced as /daɪˌaɪədoʊˈbɛnziːn/. The "di-" prefix means two, so the word indicates two iodine atoms attached to a benzene ring. The letters "io" are pronounced with a long "i" sound, and the second and third syllables are pronounced with a long "e" sound. Despite its spelling complexity, diiodobenzene is a common compound used in organic chemistry.
Diiodobenzene is a chemical compound with the molecular formula C6H4I2. It is a derivative of benzene in which two hydrogen atoms are substituted by iodine atoms. It is also known by its systematic name 1,2-diiodobenzene.
Diiodobenzene is a yellow solid at room temperature, and its melting point is around 125-128 degrees Celsius. It is sparingly soluble in water but dissolves readily in organic solvents like ethanol and diethyl ether. It has a characteristic strong aroma.
Diiodobenzene is primarily used as a building block or intermediate in organic synthesis, especially in the production of various pharmaceutical and agrochemical compounds. It undergoes a range of reactions, including halogenation, oxidation, and coupling, to form complex organic molecules.
Due to its halogenated structure, diiodobenzene possesses some reactivity and exhibits a moderate toxicity. It should be handled with caution and stored in a cool, dry place away from heat and direct sunlight. Like other iodinated compounds, it can cause skin and eye irritation upon contact. Inhalation or ingestion can also be harmful and may lead to respiratory and gastrointestinal disturbances.
In conclusion, diiodobenzene is an organic compound derived from benzene, containing two iodine substituents. It is mainly used as an intermediate in the production of various pharmaceutical and agricultural chemicals, while also demonstrating some reactivity and toxicity.
The word "diiodobenzene" is a compound of two parts: "diiodo-" and "benzene".
1. "Diiodo-" is a prefix composed of two elements: "di-" and "iodo-".
- "Di-" comes from the Greek word "dis" meaning "two" or "twice", indicating that there are two iodine atoms in the compound.
- "Iodo-" is derived from the element symbol "I" for iodine.
2. "Benzene" is a common name for a well-known aromatic compound composed of six carbon atoms arranged in a hexagonal ring with alternating single and double bonds. The word "benzene" originated from the German word "Benzin", which is derived from "Benz-" meaning "corroding" and "ene" indicating unsaturation.
